Linguistics is the scientific study of language. It involves analysing language form, language meaning, and language in context. Linguists traditionally analyse human language by observing an interplay between sound and meaning. Linguistics also deals with the social, cultural, historical and political factors that influence language, through which linguistic and language-based context is often determined. Research on language through the sub-branches of historical and evolutionary linguistics also focuses on how languages change and grow, particularly over an extended period of time.
The earliest activities in the documentation and description of language have been attributed to the 6th-century-BC Indian grammarian Pāṇini who wrote a formal description of the Sanskrit language in his Aṣṭādhyāyī.
Related areas of study include the disciplines of semiotics (the study of direct and indirect language through signs and symbols), literary criticism (the historical and ideological analysis of literature, cinema, art, or published material), translation (the conversion and documentation of meaning in written/spoken text from one language or dialect onto another), and speech-language pathology (a corrective method to cure phonetic disabilities and dis-functions at the cognitive level).
Major subdisciplines
Historical linguistics
Historical linguistics is the study of language change over time
particularly with regards to a specific language or group of languages.
Historical linguistics was among the first sub-disciplines to emerge in
linguistics, and was the most widely practised form of linguistics in
the late 19th century.
There was a shift of focus in the early twentieth century to the
synchronic approach (the systemic study of the current stage in
languages), but historical research remained a field of linguistic
inquiry. Subfields include language change and grammaticalisation studies.
Western modern historical linguistics dates from the late 18th century. It grew out of the earlier discipline of philology, the study of ancient texts and documents dating back to antiquity.
At first, historical linguistics served as the cornerstone of comparative linguistics primarily as a tool for linguistic reconstruction. Scholars were concerned chiefly with establishing language families and reconstructing prehistoric proto-languages, using the comparative method and internal reconstruction. The focus was initially on the well-known Indo-European languages, many of which had long written histories; the scholars also studied the Uralic languages,
another European language family for which less early written material
exists. Since then, there has been significant comparative linguistic
work expanding outside of European languages as well, such as on the Austronesian languages and various families of Native American languages,
among many others. Comparative linguistics is now, however, only a part
of a more broadly conceived discipline of historical linguistics. For
the Indo-European languages, comparative study is now a highly
specialized field. Most research is being carried out on the subsequent
development of these languages, in particular, the development of the
modern standard varieties.
Some scholars have undertaken studies attempting to establish
super-families, linking, for example, Indo-European, Uralic, and other
families into Nostratic.
These attempts have not been accepted widely. The information
necessary to establish relatedness becomes less available as the time
depth is increased. The time-depth of linguistic methods is limited due
to chance word resemblances and variations between language groups, but a
limit of around 10,000 years is often assumed.
The dating of the various proto-languages is also difficult; several
methods are available for dating, but only approximate results can be
obtained.
Syntax and morphology
Syntax and morphology are branches of linguistics concerned with the
order and structure of meaningful linguistic units such as words and morphemes.
Syntacticians study the rules and constraints that govern how speakers
of a language can organize words into sentences. Morphologists study
similar rules for the order of morphemes—sub-word units such as prefixes
and suffixes—and how they may be combined to form words.
While words, along with clitics, are generally accepted as being the smallest units of syntax, in most languages, if not all, many words can be related to other words by rules that collectively describe the grammar for that language. For example, English speakers recognize that the words dog and dogs are closely related, differentiated only by the plurality morpheme "-s", only found bound to noun phrases. Speakers of English, a fusional language, recognize these relations from their innate knowledge of English's rules of word formation. They infer intuitively that dog is to dogs as cat is to cats; and, in similar fashion, dog is to dog catcher as dish is to dishwasher. By contrast, Classical Chinese has very little morphology, using almost exclusively unbound morphemes ("free" morphemes) and depending on word order to convey meaning. (Most words in modern Standard Chinese ["Mandarin"], however, are compounds and most roots
are bound.) These are understood as grammars that represent the
morphology of the language. The rules understood by a speaker reflect
specific patterns or regularities in the way words are formed from
smaller units in the language they are using, and how those smaller
units interact in speech. In this way, morphology is the branch of
linguistics that studies patterns of word formation within and across
languages and attempts to formulate rules that model the knowledge of
the speakers of those languages.
Phonological and orthographic modifications between a base word and its origin may be partial to literacy
skills. Studies have indicated that the presence of modification in
phonology and orthography makes morphologically complex words harder to
understand and that the absence of modification between a base word and
its origin makes morphologically complex words easier to understand.
Morphologically complex words are easier to comprehend when they include
a base word.
Polysynthetic languages, such as Chukchi,
have words composed of many morphemes. The Chukchi word
"təmeyŋəlevtpəγtərkən", for example, meaning "I have a fierce headache",
is composed of eight morphemes t-ə-meyŋ-ə-levt-pəγt-ə-rkən that may be glossed. The morphology of such languages allows for each consonant and vowel to be understood as morphemes, while the grammar of the language indicates the usage and understanding of each morpheme.
The discipline that deals specifically with the sound changes occurring within morphemes is morphophonology.
Semantics and pragmatics
Semantics and pragmatics are branches of linguistics concerned with
meaning. These subfields have traditionally been divided by the role of
linguistic and social context in the determination of meaning. Semantics
in this conception is concerned with core meanings and pragmatics
concerned with meaning in context. Pragmatics encompasses speech act theory, conversational implicature, talk in interaction and other approaches to language behavior in philosophy, sociology, linguistics and anthropology. Unlike semantics,
which examines meaning that is conventional or "coded" in a given
language, pragmatics studies how the transmission of meaning depends not
only on structural and linguistic knowledge (grammar, lexicon, etc.) of the speaker and listener but also on the context of the utterance, any pre-existing knowledge about those involved, the inferred intent of the speaker, and other factors. In that respect, pragmatics explains how language users are able to overcome apparent ambiguity since meaning relies on the manner, place, time, etc. of an utterance.
Phonetics and phonology
Phonetics and phonology are branches of linguistics concerned with
sounds (or the equivalent aspects of sign languages). Phonetics is
largely concerned with the physical aspects of sounds such as their
acoustics, production, and perception. Phonology is concerned with the
linguistic abstractions and categorizations of sounds.
Language varieties
Languages exist on a wide continuum of conventionalization with
blurry divisions between concepts such as dialects and languages.
Languages can undergo internal changes which lead to the development of
subvarieties such as linguistic registers,
accents, and dialects. Similarly, languages can undergo changes caused
by contact with speakers of other languages, and new language varieties
may be born from these contact situations through the process of language genesis.
Contact varieties
Contact varieties such as pidgins and creoles are language varieties
that often arise in situations of sustained contact between communities
that speak different languages. Pidgins
are language varieties with limited conventionalization where ideas are
conveyed through simplified grammars that may grow more complex as
linguistic contact continues. Creole languages
are language varieties similar to pidgins but with greater
conventionalization and stability. As children grow up in contact
situations, they may learn a local pidgin as their native language.
Through this process of acquisition and transmission, new grammatical
features and lexical items are created and introduced to fill gaps in the pidgin eventually developing into a complete language.
Not all language contact situations result in the development of a
pidgin or creole, and researchers have studied the features of contact
situations that make contact varieties more likely to develop. Often
these varieties arise in situations of colonization and enslavement,
where power imbalances prevent the contact groups from learning the
other's language but sustained contact is nevertheless maintained. The
subjugated language in the power relationship is the substrate language, while the dominant language serves as the superstrate. Often the words and lexicon of a contact variety come from the superstrate, making it the lexifier, while grammatical structures come from the substrate, but this is not always the case.
Dialect
A dialect is a variety of language that is characteristic of a particular group among the language's speakers.
The group of people who are the speakers of a dialect are usually bound
to each other by social identity. This is what differentiates a dialect
from a register or a discourse,
where in the latter case, cultural identity does not always play a
role. Dialects are speech varieties that have their own grammatical and
phonological rules, linguistic features, and stylistic aspects, but have
not been given an official status as a language. Dialects often move on
to gain the status of a language due to political and social reasons.
Other times, dialects remain marginalized, particularly when they are
associated with marginalized social groups.
Differentiation amongst dialects (and subsequently, languages) is based
upon the use of grammatical rules, syntactic rules, and stylistic
features, though not always on lexical use or vocabulary. The popular
saying that "a language is a dialect with an army and navy" is attributed as a definition formulated by Max Weinreich.
"We may as individuals be rather fond of our own dialect. This should not make us think, though, that it is actually any better than any other dialect. Dialects are not good or bad, nice or nasty, right or wrong – they are just different from one another, and it is the mark of a civilised society that it tolerates different dialects just as it tolerates different races, religions and sexes."
Standard language
When a dialect is documented sufficiently through the linguistic
description of its grammar, which has emerged through the consensual
laws from within its community, it gains political and national
recognition through a country or region's policies. That is the stage
when a language is considered a standard variety, one whose grammatical laws have now stabilised from within the consent of speech community
participants, after sufficient evolution, improvisation, correction,
and growth. The English language, besides perhaps the French language,
may be examples of languages that have arrived at a stage where they are
said to have become standard varieties.
Relativity
As constructed popularly through the Sapir–Whorf hypothesis,
relativists believe that the structure of a particular language is
capable of influencing the cognitive patterns through which a person
shapes his or her world view.
Universalists believe that there are commonalities between human
perception as there is in the human capacity for language, while
relativists believe that this varies from language to language and
person to person. While the Sapir–Whorf hypothesis is an elaboration of
this idea expressed through the writings of American linguists Edward Sapir and Benjamin Lee Whorf, it was Sapir's student Harry Hoijer who termed it thus. The 20th century German linguist Leo Weisgerber
also wrote extensively about the theory of relativity. Relativists
argue for the case of differentiation at the level of cognition and in
semantic domains. The emergence of cognitive linguistics in the 1980s also revived an interest in linguistic relativity. Thinkers like George Lakoff have argued that language reflects different cultural metaphors, while the French philosopher of language Jacques Derrida's writings, especially about deconstruction,
have been seen to be closely associated with the relativist movement in
linguistics, for which he was heavily criticized in the media at the
time of his death.
Structures
Linguistic structures are pairings of meaning and form. Any particular pairing of meaning and form is a Saussurean sign.
For instance, the meaning "cat" is represented worldwide with a wide
variety of different sound patterns (in oral languages), movements of
the hands and face (in sign languages), and written symbols (in written languages). Linguistic patterns have proven their importance for the knowledge engineering field especially with the ever-increasing amount of available data.
Linguists focusing on structure attempt to understand the rules
regarding language use that native speakers know (not always
consciously). All linguistic structures can be broken down into
component parts that are combined according to (sub)conscious rules,
over multiple levels of analysis. For instance, consider the structure
of the word "tenth" on two different levels of analysis. On the level
of internal word structure (known as morphology), the word "tenth" is
made up of one linguistic form indicating a number and another form
indicating ordinality. The rule governing the combination of these
forms ensures that the ordinality marker "th" follows the number "ten."
On the level of sound structure (known as phonology), structural
analysis shows that the "n" sound in "tenth" is made differently from
the "n" sound in "ten" spoken alone. Although most speakers of English
are consciously aware of the rules governing internal structure of the
word pieces of "tenth", they are less often aware of the rule governing
its sound structure. Linguists focused on structure find and analyze
rules such as these, which govern how native speakers use language.
Grammar
Grammar is a system of rules which governs the production and use of utterances in a given language. These rules apply to sound as well as meaning, and include componential subsets of rules, such as those pertaining to phonology (the organisation of phonetic sound systems), morphology (the formation and composition of words), and syntax (the formation and composition of phrases and sentences). Modern frameworks that deal with the principles of grammar include structural and functional linguistics, and generative linguistics.
Sub-fields that focus on a grammatical study of language include the following.
- Phonetics, the study of the physical properties of speech sound production and perception, and delves into their acoustic and articulatory properties
- Phonology, the study of sounds as abstract elements in the speaker's mind that distinguish meaning (phonemes)
- Morphology, the study of morphemes, or the internal structures of words and how they can be modified
- Syntax, the study of how words combine to form grammatical phrases and sentences
- Semantics, the study of the meaning of words (lexical semantics) and fixed word combinations (phraseology), and how these combine to form the meanings of sentences as well as manage and resolve ambiguity.
- Pragmatics, the study of how utterances are used in communicative acts, and the role played by situational context and non-linguistic knowledge in the transmission of meaning
- Discourse analysis, the analysis of language use in texts (spoken, written, or signed)
- Stylistics, the study of linguistic factors (rhetoric, diction, stress) that place a discourse in context
- Semiotics, the study of signs and sign processes (semiosis), indication, designation, likeness, analogy, metaphor, symbolism, signification, and communication
Discourse
Discourse
is language as social practice (Baynham, 1995) and is a multilayered
concept. As a social practice, discourse embodies different ideologies
through written and spoken texts. Discourse analysis can examine or
expose these ideologies. Discourse influences genre, which is chosen
in response to different situations and finally, at micro level,
discourse influences language as text (spoken or written) at the
phonological or lexico-grammatical level. Grammar and discourse are
linked as parts of a system.
A particular discourse becomes a language variety when it is used in
this way for a particular purpose, and is referred to as a register. There may be certain lexical
additions (new words) that are brought into play because of the
expertise of the community of people within a certain domain of
specialization. Registers and discourses therefore differentiate
themselves through the use of vocabulary,
and at times through the use of style too. People in the medical
fraternity, for example, may use some medical terminology in their
communication that is specialized to the field of medicine. This is
often referred to as being part of the "medical discourse", and so on.
Lexicon
The lexicon is a catalogue of words and terms that are stored in a speaker's mind. The lexicon consists of words and bound morphemes, which are parts of words that can't stand alone, like affixes.
In some analyses, compound words and certain classes of idiomatic
expressions and other collocations are also considered to be part of the
lexicon. Dictionaries represent attempts at listing, in alphabetical
order, the lexicon of a given language; usually, however, bound
morphemes are not included. Lexicography, closely linked with the domain of semantics, is the science of mapping the words into an encyclopedia or a dictionary. The creation and addition of new words (into the lexicon) is called coining or neologization, and the new words are called neologisms.
It is often believed that a speaker's capacity for language lies
in the quantity of words stored in the lexicon. However, this is often
considered a myth by linguists. The capacity for the use of language is
considered by many linguists to lie primarily in the domain of grammar,
and to be linked with competence,
rather than with the growth of vocabulary. Even a very small lexicon is
theoretically capable of producing an infinite number of sentences.
Style
Stylistics also involves the study of written, signed, or spoken discourse through varying speech communities, genres, and editorial or narrative formats in the mass media.
It involves the study and interpretation of texts for aspects of their
linguistic and tonal style. Stylistic analysis entails the analysis of
description of particular dialects and registers used by speech communities. Stylistic features include rhetoric, diction, stress, satire, irony,
dialogue, and other forms of phonetic variations. Stylistic analysis
can also include the study of language in canonical works of literature,
popular fiction, news, advertisements, and other forms of communication
in popular culture as well. It is usually seen as a variation in
communication that changes from speaker to speaker and community to
community. In short, Stylistics is the interpretation of text.
In the 1960s, Jacques Derrida,
for instance, further distinguished between speech and writing, by
proposing that written language be studied as a linguistic medium of
communication in itself. Palaeography is therefore the discipline that studies the evolution of written scripts (as signs and symbols) in language. The formal study of language also led to the growth of fields like psycholinguistics, which explores the representation and function of language in the mind; neurolinguistics, which studies language processing in the brain; biolinguistics, which studies the biology and evolution of language; and language acquisition, which investigates how children and adults acquire the knowledge of one or more languages.
Approaches
Humanistic
A semiotic tradition of linguistic research considers language as arising from the interaction of a semantic system and a sign system. The organisation of linguistic levels is considered computational. Linguistics is essentially seen as relating to social and cultural studies because different languages are shaped in social interaction by the speech community. Frameworks representing the humanistic view of language include structural linguistics, among others.
Structural analysis means dissecting each linguistic level:
phonetic, morphological, syntactic, and discourse, to the smallest
units. These are collected into inventories (e.g. phoneme, morpheme and
lexical classes, and phrase types) to study their interconnectedness
within a hierarchy of structures and layers.
Functional analysis adds to structural analysis the assignment of
semantic and other functional roles that each unit may have. For
example, a noun phrase may function as the subject or object of the
sentence; or the agent or patient.
Functional linguistics, or functional grammar, is a branch of structural linguistics. In the humanistic reference, the terms structuralism and functionalism
are related to their meaning in other human sciences. The difference
between formal and functional structuralism lies in the way that the two
approaches explain why languages have the properties they have.
Functional explanation entails the idea that language is a tool for communication,
or that communication is the primary function of language. Linguistic
forms are consequently explained by an appeal to their functional value,
or usefulness. Other structuralist approaches take the perspective that
form follows from the inner mechanisms of the binary or multilayered
language system.
Biological
Other linguistics frameworks take as their starting point the notion that language is a biological phenomenon in humans. Generative Grammar is the study of an innate linguistic structure. In contrast to structural linguistics, Generative Grammar rejects the notions that meaning or social interaction affects language. Instead, all human languages are based on a crystallised structure which may have been caused by a mutation exclusively in humans. The study of linguistics is considered as the study of this hypothesised structure.
Cognitive Linguistics, in contrast, rejects the notion of innate grammar, and studies how the human brain creates linguistic constructions from event schemas. The impact of cognitive constraints and biases on human language are studied, as are also frames, idealised cognitive models, and memes. A closely related approach is evolutionary linguistics which includes the study of linguistic units as cultural replicators. It is possible to study how language replicates and adapts to the mind of the individual or the speech community.
The generative versus evolutionary approach are sometimes called formalism and functionalism, respectively. This reference is however different from the use of the terms in human sciences.
Methodology
Linguistics is primarily descriptive.
Linguists describe and explain features of language without making
subjective judgments on whether a particular feature or usage is "good"
or "bad". This is analogous to practice in other sciences: a zoologist
studies the animal kingdom without making subjective judgments on
whether a particular species is "better" or "worse" than another.
Prescription,
on the other hand, is an attempt to promote particular linguistic
usages over others, often favouring a particular dialect or "acrolect". This may have the aim of establishing a linguistic standard,
which can aid communication over large geographical areas. It may also,
however, be an attempt by speakers of one language or dialect to exert
influence over speakers of other languages or dialects (see Linguistic imperialism). An extreme version of prescriptivism can be found among censors,
who attempt to eradicate words and structures that they consider to be
destructive to society. Prescription, however, may be practised
appropriately in language instruction, like in ELT,
where certain fundamental grammatical rules and lexical items need to
be introduced to a second-language speaker who is attempting to acquire the language.
Anthropology
The objective of describing languages is often to uncover cultural knowledge about communities. The use of anthropological
methods of investigation on linguistic sources leads to the discovery
of certain cultural traits among a speech community through its
linguistic features. It is also widely used as a tool in language documentation, with an endeavour to curate endangered languages.
However, linguistic inquiry now uses the anthropological method to
understand cognitive, historical, sociolinguistic and historical
processes that languages undergo as they change and evolve, as well as
general anthropological inquiry uses the linguistic method to excavate
into culture. In all aspects, anthropological inquiry usually uncovers
the different variations and relativities that underlie the usage of
language.
Sources
Most contemporary linguists work under the assumption that spoken data and signed data are more fundamental than written data. This is because
- Speech appears to be universal to all human beings capable of producing and perceiving it, while there have been many cultures and speech communities that lack written communication;
- Features appear in speech which aren't always recorded in writing, including phonological rules, sound changes, and speech errors;
- All natural writing systems reflect a spoken language (or potentially a signed one), even with pictographic scripts like Dongba writing Naxi homophones with the same pictogram, and text in writing systems used for two languages changing to fit the spoken language being recorded;
- Speech evolved before human beings invented writing;
- People learnt to speak and process spoken language more easily and earlier than they did with writing.
Nonetheless, linguists agree that the study of written language can be worthwhile and valuable. For research that relies on corpus linguistics and computational linguistics,
written language is often much more convenient for processing large
amounts of linguistic data. Large corpora of spoken language are
difficult to create and hard to find, and are typically transcribed and written. In addition, linguists have turned to text-based discourse occurring in various formats of computer-mediated communication as a viable site for linguistic inquiry.
The study of writing systems themselves, graphemics, is, in any case, considered a branch of linguistics.
Analysis
Before the 20th century, linguists analysed language on a diachronic
plane, which was historical in focus. This meant that they would
compare linguistic features and try to analyse language from the point
of view of how it had changed between then and later. However, with Saussurean linguistics in the 20th century, the focus shifted to a more synchronic
approach, where the study was more geared towards analysis and
comparison between different language variations, which existed at the
same given point of time.
At another level, the syntagmatic
plane of linguistic analysis entails the comparison between the way
words are sequenced, within the syntax of a sentence. For example, the
article "the" is followed by a noun, because of the syntagmatic relation
between the words. The paradigmatic plane on the other hand, focuses on an analysis that is based on the paradigms
or concepts that are embedded in a given text. In this case, words of
the same type or class may be replaced in the text with each other to
achieve the same conceptual understanding.
History
Nomenclature
Before the 20th century, the term philology, first attested in 1716, was commonly used to refer to the study of language, which was then predominantly historical in focus. Since Ferdinand de Saussure's insistence on the importance of synchronic analysis, however, this focus has shifted and the term philology is now generally used for the "study of a language's grammar, history, and literary tradition", especially in the United States (where philology has never been very popularly considered as the "science of language").
Although the term "linguist" in the sense of "a student of language" dates from 1641, the term "linguistics" is first attested in 1847. It is now the usual term in English for the scientific study of language, though linguistic science is sometimes used.
Linguistics is a multi-disciplinary field of research that combines tools from natural sciences, social sciences, and the humanities. Many linguists, such as David Crystal, conceptualize the field as being primarily scientific. The term linguist
applies to someone who studies language or is a researcher within the
field, or to someone who uses the tools of the discipline to describe
and analyse specific languages.
Early grammarians
The formal study of language began in India with Pāṇini, the 6th century BC grammarian who formulated 3,959 rules of Sanskrit morphology. Pāṇini's systematic classification of the sounds of Sanskrit into consonants and vowels, and word classes, such as nouns and verbs, was the first known instance of its kind. In the Middle East, Sibawayh, a non-Arab, made a detailed description of Arabic in AD 760 in his monumental work, Al-kitab fi al-nahw (الكتاب في النحو, The Book on Grammar), the first known author to distinguish between sounds and phonemes (sounds as units of a linguistic system). Western interest in the study of languages began somewhat later than in the East,
but the grammarians of the classical languages did not use the same
methods or reach the same conclusions as their contemporaries in the
Indic world. Early interest in language in the West was a part of
philosophy, not of grammatical description. The first insights into
semantic theory were made by Plato in his Cratylus dialogue,
where he argues that words denote concepts that are eternal and exist
in the world of ideas. This work is the first to use the word etymology to describe the history of a word's meaning. Around 280 BC, one of Alexander the Great's successors founded a university (see Musaeum) in Alexandria, where a school of philologists studied the ancient texts in and taught Greek to speakers of other languages. While this school was the first to use the word "grammar" in its modern sense, Plato had used the word in its original meaning as "téchnē grammatikḗ" (Τέχνη Γραμματική), the "art of writing", which is also the title of one of the most important works of the Alexandrine school by Dionysius Thrax. Throughout the Middle Ages,
the study of language was subsumed under the topic of philology, the
study of ancient languages and texts, practised by such educators as Roger Ascham, Wolfgang Ratke, and John Amos Comenius.
Comparative philology
In the 18th century, the first use of the comparative method by William Jones sparked the rise of comparative linguistics. Bloomfield attributes "the first great scientific linguistic work of the world" to Jacob Grimm, who wrote Deutsche Grammatik.
It was soon followed by other authors writing similar comparative
studies on other language groups of Europe. The study of language was
broadened from Indo-European to language in general by Wilhelm von Humboldt, of whom Bloomfield asserts:
This study received its foundation at the hands of the Prussian statesman and scholar Wilhelm von Humboldt (1767–1835), especially in the first volume of his work on Kavi, the literary language of Java, entitled Über die Verschiedenheit des menschlichen Sprachbaues und ihren Einfluß auf die geistige Entwickelung des Menschengeschlechts (On the Variety of the Structure of Human Language and its Influence upon the Mental Development of the Human Race).
20th century developments
There
was a shift of focus from historical and comparative linguistics to
synchronic analysis in early 20th century. Structural analysis was
improved by Leonard Bloomfield, Louis Hjelmslev; and Zellig Harris who also developed methods of discourse analysis. Functional analysis was developed by the Prague linguistic circle and André Martinet. As sound recording devices became commonplace in the 1960s, dialectal recordings were made and archived, and the audio-lingual method
provided a technological solution to foreign language learning. The
1960s also saw a new rise of comparative linguistics: the study of language universals in linguistic typology. Towards the end of the century the field of linguistics became divided into further areas of interest with the advent of language technology and digitalised corpora.
Areas of research
Ecolinguistics
Ecolinguistics
explores the role of language in the life-sustaining interactions of
humans, other species and the physical environment. The first aim is to
develop linguistic theories which see humans not only as part of
society, but also as part of the larger ecosystems that life depends on.
The second aim is to show how linguistics can be used to address key
ecological issues, from climate change and biodiversity loss to environmental justice.
Sociolinguistics
Sociolinguistics
is the study of how language is shaped by social factors. This
sub-discipline focuses on the synchronic approach of linguistics, and
looks at how a language in general, or a set of languages, display
variation and varieties at a given point in time. The study of language
variation and the different varieties of language through dialects,
registers, and idiolects can be tackled through a study of style, as
well as through analysis of discourse. Sociolinguists research both
style and discourse in language, as well as the theoretical factors that
are at play between language and society.
Developmental linguistics
Developmental linguistics is the study of the development of linguistic ability in individuals, particularly the acquisition of language
in childhood. Some of the questions that developmental linguistics
looks into is how children acquire different languages, how adults can
acquire a second language, and what the process of language acquisition
is.
Neurolinguistics
Neurolinguistics
is the study of the structures in the human brain that underlie grammar
and communication. Researchers are drawn to the field from a variety of
backgrounds, bringing along a variety of experimental techniques as
well as widely varying theoretical perspectives. Much work in
neurolinguistics is informed by models in psycholinguistics and theoretical linguistics,
and is focused on investigating how the brain can implement the
processes that theoretical and psycholinguistics propose are necessary
in producing and comprehending language. Neurolinguists study the
physiological mechanisms by which the brain processes information
related to language, and evaluate linguistic and psycholinguistic
theories, using aphasiology, brain imaging,
electrophysiology, and computer modelling. Amongst the structures of
the brain involved in the mechanisms of neurolinguistics, the cerebellum
which contains the highest numbers of neurons has a major role in terms
of predictions required to produce language.
Applied linguistics
Linguists are largely concerned with finding and describing the generalities and varieties both within particular languages and among all languages. Applied linguistics
takes the results of those findings and "applies" them to other areas.
Linguistic research is commonly applied to areas such as language education, lexicography, translation, language planning, which involves governmental policy implementation related to language use, and natural language processing. "Applied linguistics" has been argued to be something of a misnomer.
Applied linguists actually focus on making sense of and engineering
solutions for real-world linguistic problems, and not literally
"applying" existing technical knowledge from linguistics. Moreover, they
commonly apply technical knowledge from multiple sources, such as
sociology (e.g., conversation analysis) and anthropology. (Constructed language fits under Applied linguistics.)
Today, computers are widely used in many areas of applied linguistics. Speech synthesis and speech recognition use phonetic and phonemic knowledge to provide voice interfaces to computers. Applications of computational linguistics in machine translation, computer-assisted translation, and natural language processing
are areas of applied linguistics that have come to the forefront. Their
influence has had an effect on theories of syntax and semantics, as
modelling syntactic and semantic theories on computers constraints.
Linguistic analysis is a sub-discipline of applied linguistics used by many governments to verify the claimed nationality of people seeking asylum who do not hold the necessary documentation to prove their claim. This often takes the form of an interview by personnel in an immigration department. Depending on the country, this interview is conducted either in the asylum seeker's native language through an interpreter or in an international lingua franca like English.
Australia uses the former method, while Germany employs the latter; the
Netherlands uses either method depending on the languages involved.
Tape recordings of the interview then undergo language analysis, which
can be done either by private contractors or within a department of the
government. In this analysis, linguistic features of the asylum seeker
are used by analysts to make a determination about the speaker's
nationality. The reported findings of the linguistic analysis can play a
critical role in the government's decision on the refugee status of the
asylum seeker.
Semiotics
Semiotics
is the study of sign processes (semiosis), or signification and
communication, signs, and symbols, both individually and grouped into
sign systems, including the study of how meaning is constructed and
understood. Semioticians often do not restrict themselves to linguistic
communication when studying the use of signs but extend the meaning of
"sign" to cover all kinds of cultural symbols. Nonetheless, semiotic
disciplines closely related to linguistics are literary studies, discourse analysis, text linguistics, and philosophy of language. Semiotics, within the linguistics paradigm, is the study of the relationship between language and culture. Historically, Edward Sapir and Ferdinand De Saussure's
structuralist theories influenced the study of signs extensively until
the late part of the 20th century, but later, post-modern and
post-structural thought, through language philosophers including Jacques Derrida, Mikhail Bakhtin, Michel Foucault,
and others, have also been a considerable influence on the discipline
in the late part of the 20th century and early 21st century.
These theories emphasize the role of language variation, and the idea
of subjective usage, depending on external elements like social and
cultural factors, rather than merely on the interplay of formal
elements.
Language documentation
Language documentation
combines anthropological inquiry (into the history and culture of
language) with linguistic inquiry, in order to describe languages and
their grammars. Lexicography
involves the documentation of words that form a vocabulary. Such a
documentation of a linguistic vocabulary from a particular language is
usually compiled in a dictionary. Computational linguistics
is concerned with the statistical or rule-based modeling of natural
language from a computational perspective. Specific knowledge of
language is applied by speakers during the act of translation and interpretation, as well as in language education – the teaching of a second or foreign language. Policy makers work with governments to implement new plans in education and teaching which are based on linguistic research.
Since the inception of the discipline of linguistics, linguists have been concerned with describing and analysing previously undocumented languages. Starting with Franz Boas
in the early 1900s, this became the main focus of American linguistics
until the rise of formal structural linguistics in the mid-20th century.
This focus on language documentation was partly motivated by a concern
to document the rapidly disappearing
languages of indigenous peoples. The ethnographic dimension of the
Boasian approach to language description played a role in the
development of disciplines such as sociolinguistics, anthropological linguistics, and linguistic anthropology, which investigate the relations between language, culture, and society.
The emphasis on linguistic description and documentation has also
gained prominence outside North America, with the documentation of
rapidly dying indigenous languages becoming a primary focus in many
university programmes in linguistics. Language description is a
work-intensive endeavour, usually requiring years of field work in the
language concerned, so as to equip the linguist to write a sufficiently
accurate reference grammar. Further, the task of documentation requires
the linguist to collect a substantial corpus in the language in
question, consisting of texts and recordings, both sound and video,
which can be stored in an accessible format within open repositories,
and used for further research.
Translation
The sub-field of translation
includes the translation of written and spoken texts across media, from
digital to print and spoken. To translate literally means to transmute
the meaning from one language into another. Translators are often
employed by organizations such as travel agencies and governmental
embassies to facilitate communication between two speakers who do not
know each other's language. Translators are also employed to work within
computational linguistics setups like Google Translate,
which is an automated program to translate words and phrases between
any two or more given languages. Translation is also conducted by
publishing houses, which convert works of writing from one language to
another in order to reach varied audiences. Academic translators
specialize in or are familiar with various other disciplines such as
technology, science, law, economics, etc.
Biolinguistics
Biolinguistics
is the study of the biology and evolution of language. It is a highly
interdisciplinary field, including linguists, biologists,
neuroscientists, psychologists, mathematicians, and others. By shifting
the focus of investigation in linguistics to a comprehensive scheme that
embraces the natural sciences, it seeks to yield a framework by which
the fundamentals of the faculty of language are understood.
Clinical linguistics
Clinical linguistics is the application of linguistic theory to the field of speech-language pathology. Speech language pathologists work on corrective measures to treat communication and swallowing disorders.
Chaika (1990) showed that people with schizophrenia who display
speech disorders like rhyming inappropriately have attentional
dysfunction, as when a patient was shown a color chip and then asked to
identify it, responded "looks like clay. Sounds like gray. Take you for a
roll in the hay. Heyday, May Day." The color chip was actually
clay-colored, so his first response was correct.'
However, most people suppress or ignore words which rhyme with
what they've said unless they are deliberately producing a pun, poem or
rap. Even then, the speaker shows connection between words chosen for
rhyme and an overall meaning in discourse. People with schizophrenia
with speech dysfunction show no such relation between rhyme and reason.
Some even produce stretches of gibberish combined with recognizable
words.
Computational linguistics
Computational linguistics
is the study of linguistic issues in a way that is "computationally
responsible", i.e., taking careful note of computational consideration
of algorithmic specification and computational complexity, so that the
linguistic theories devised can be shown to exhibit certain desirable
computational properties and their implementations. Computational
linguists also work on computer language and software development.
Evolutionary linguistics
Evolutionary linguistics is the interdisciplinary study of the emergence of the language faculty through human evolution, and also the application of evolutionary theory
to the study of cultural evolution among different languages. It is
also a study of the dispersal of various languages across the globe,
through movements among ancient communities.
Forensic linguistics
Forensic linguistics is the application of linguistic analysis to forensics.
Forensic analysis investigates the style, language, lexical use, and
other linguistic and grammatical features used in the legal context to
provide evidence in courts of law. Forensic linguists have also used
their expertise in the framework of criminal cases.
