Major subdisciplines
Historical linguistics
Historical linguistics is the study of how language changes in history, particularly with regard to a specific language or a group of languages. Western trends in historical linguistics date back to roughly the late 18th century, when the discipline grew out of philology, the study of ancient texts and oral traditions. Historical linguistics emerged as one of the first few sub-disciplines in the field, and was most widely practiced during the late 19th century. Despite a shift in focus in the twentieth century towardsSyntax 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,Semantics and pragmatics
Semantics and pragmatics are branches of linguistics concerned with meaning. These subfields have traditionally been divided according to aspects of meaning thought to arise from the grammar versus linguistic and social context. Semantics in this conception is concerned with grammatical and lexical meanings and pragmatics concerned with meaning in context. The framework of formal semantics studies the denotations of sentences and the way they are composed from the meanings of their constituent expressions. Formal semantics draws heavily onPhonetics 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 articulation, acoustics, production, and perception. Phonology is concerned with the linguistic abstractions and categorizations of sounds.Typology
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 ofContact 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 aStandard 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 aRelativity
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 studentStructures
Linguistic structures are pairings of meaning and form. Any particular pairing of meaning and form is aGrammar
Grammar is a system of rules which governs the production and use ofDiscourse
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 aLexicon
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, likeStyle
Approaches
Humanistic
The fundamental principle of humanistic linguistics is that language is an invention created by people. A semiotic tradition of linguistic research considers language a sign system which arises from the interaction of meaning and form. 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, lexical classes, 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 theBiological
Approaches such as cognitive linguistics and generative grammar study linguistic cognition with a view towards uncovering the biology, biological underpinnings of language. In Generative Grammar, these underpinning are understood as including Linguistic nativism, innate domain-specific grammatical knowledge. Thus, one of the central concerns of the approach is to discover what aspects of linguistic knowledge are innate and which are not. Cognitive Linguistics, in contrast, rejects the notion of innate grammar, and studies how the human mind creates linguistic Construction grammar, constructions from event schema (psychology), schemas, and the impact of cognitive constraints and Cognitive bias, biases on human language. In cognitive linguistics, language is approached via the senses. A closely related approach is evolutionary linguistics which includes the study of linguistic units as Memetics, cultural replicators. It is possible to study how language Self-replication, replicates and Adaptation, adapts to the mind of the individual or the speech community. Construction grammar is a framework which applies the meme concept to the study of syntax. The generative versus evolutionary approach are sometimes called Structuralism (biology), formalism and Adaptationism, functionalism, respectively. This reference is however different from the use of the terms in Humanities, human sciences.Methodology
Linguistics is primarily descriptive linguistics, 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. Linguistic prescription, 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 Standard language, 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 censorship, censors, who attempt to eradicate words and structures that they consider to be destructive to society. Prescription, however, may be practised appropriately in language education, language instruction, like in English language teaching, ELT, where certain fundamental grammatical rules and lexical items need to be introduced to a second-language speaker who is attempting to language acquisition, acquire the language.Sources
Most contemporary linguists work under the assumption that spoken language, spoken data and Sign language, signed data are more fundamental than written language, 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 language, Naxi homophones with the same pictogram, and text in writing systems used for List of languages by writing system, two languages changing to fit the spoken language being recorded; * Speech evolved before human beings invented writing; * Individuals learn to speak and process spoken language more easily and earlier than they do 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 transcription (linguistics), 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 linguistics, 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 the rise ofHistory
The earliest activities in the linguistic description, description of language have been attributed to the 6th century BC, 6th-century-BC Indian grammarian Pāṇini who wrote a Formal grammar, formal description of the Sanskrit, Sanskrit language in his '. Today, modern-day theories on generative grammar, grammar employ many of the principles that were laid down then.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 (linguistics), 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 Interdisciplinarity, multi-disciplinary field of research that combines tools from natural sciences, social sciences, formal 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 language, 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 Persian, made a detailed description of Arabic in AD 760 in his monumental work, ''Al-kitab fii an-naħw'' (, ''The Book on Grammar''), the first known author to distinguish between phonetics, sounds and phonology, 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), ''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 language, 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 "Art of Grammar, téchnē grammatikḗ" (), 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 (philologist), 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 languages, Indo-European to language in general by Wilhelm von Humboldt, of whom Bloomfield asserts: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 corpus linguistics, corpora.Areas of research
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 Language acquisition, the acquisition of language in childhood. Some of the questions that developmental linguistics looks into are 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 descriptive linguistics, 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 language interpretation, 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.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 Language interpretation, 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 language documentation, undocumented languages. Starting with Franz Boas in the early 1900s, this became the main focus of American linguistics until the rise of formal linguistics in the mid-20th century. This focus on language documentation was partly motivated by a concern to document the rapidly language death, 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 focus in some 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.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 disorders, 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 study of the emergence of the language faculty through human evolution, and also the application of evolution, 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. Evolutionary linguistics 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 language are understood.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.See also
