Traditional areas of linguistic analysis correspond to syntax (rules governing the structure of sentences), semantics (meaning), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language), and pragmatics (how social context contributes to meaning).[6] Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions.[7]
Linguistics encompasses many branches and subfields that span both theoretical and practical applications.[8] Theoretical linguistics (including traditional descriptive linguistics) is concerned with understanding the universal and fundamental nature of language and developing a general theoretical framework for describing it.[9] Applied linguistics seeks to utilize the scientific findings of the study of language for practical purposes, such as developing methods of improving language education and literacy.[10]
Linguistic features may be studied through a variety of perspectives: synchronically (by describing the structure of a language at a specific point in time) or diachronically (through the historical development of a language over a period of time), in monolinguals or in multilinguals, among children or amongst adults, in terms of how it is being learnt or how it was acquired, as abstract objects or as cognitive structures, through written texts or through oral elicitation, and finally through mechanical data collection or through practical fieldwork.[11]
Linguistics emerged from the field of philology, of which some branches are more qualitative and holistic in approach.[4] Today, philology and linguistics are now variably described as related fields, subdisciplines, or separate fields of language study but, by and large, linguistics can be seen as an umbrella term.[12] Linguistics is also related to the philosophy of language, stylistics, rhetoric, semiotics, lexicography, and translation.
Historical linguistics is the study of how language changes over 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.[13]
Historical linguistics emerged as one of the first few sub-disciplines in the field, and was most widely practised during the late 19th century.[14] Despite a shift in focus in the 20th century towards formalism and generative grammar, which studies the universal properties of language, historical research today still remains a significant field of linguistic inquiry. Subfields of the discipline include language change and grammaticalization.[15]
Historical linguistics studies language change either diachronically (through a comparison of different time periods in the past and present) or in a synchronic manner (by observing developments between different variations that exist within the current linguistic stage of a language).[citation needed]
At first, historical linguistics was the cornerstone of comparative linguistics, which involves a study of the relationship between different languages.[16] At that time, scholars of historical linguistics were only concerned with creating different categories of language families, and reconstructing prehistoric proto-languages by using both the comparative method and the method of internal reconstruction. Internal reconstruction is the method by which an element that contains a certain meaning is re-used in different contexts or environments where there is a variation in either sound or analogy.[16][better source needed]
The reason for this had been to describe well-known Indo-European languages, many of which had detailed documentation and long written histories. Scholars of historical linguistics also studied Uralic languages, another European language family for which very little written material existed back then. After that, there also followed significant work on the corpora of other languages, such as the Austronesian languages and the Native American language families.
The above approach of comparativism in linguistics is now, however, only a small part of the much broader discipline called historical linguistics. The comparative study of specific Indo-European languages is considered a highly specialized field today, while comparative research is carried out over the subsequent internal developments in a language: in particular, over the development of modern standard varieties of languages, and over the development of a language from its standardized form to its varieties.[citation needed]
For instance, some scholars also tried to establish super-families, linking, for example, Indo-European, Uralic, and other language families to Nostratic.[17] While these attempts are still not widely accepted as credible methods, they provide necessary information to establish relatedness in language change. This is generally hard to find for events long ago, due to the occurrence of chance word resemblances and variations between language groups. A limit of around 10,000 years is often assumed for the functional purpose of conducting research.[18] It is also hard to date various proto-languages. Even though several methods are available, these languages can be dated only approximately.[19]
In modern historical linguistics, we examine how languages change over time, focusing on the relationships between dialects within a specific period. This includes studying morphological, syntactical, and phonetic shifts. Connections between dialects in the past and present are also explored.[20]
Syntax is the study of how words and morphemes combine to form larger units such as phrases and sentences. Central concerns of syntax include word order, grammatical relations,constituency,[21] agreement, the nature of crosslinguistic variation, and the relationship between form and meaning. There are numerous approaches to syntax that differ in their central assumptions and goals.
Morphology is the study of words, including the principles by which they are formed, and how they relate to one another within a language.[22][23] Most approaches to morphology investigate the structure of words in terms of morphemes, which are the smallest units in a language with some independent meaning. Morphemes include roots that can exist as words by themselves, but also categories such as affixes that can only appear as part of a larger word. For example, in English the root catch and the suffix -ing are both morphemes; catch may appear as its own word, or it may be combined with -ing to form the new word catching. Morphology also analyzes how words behave as parts of speech, and how they may be inflected to express grammatical categories including number, tense, and aspect. Concepts such as productivity are concerned with how speakers create words in specific contexts, which evolves over the history of a language.
Semantics and pragmatics are branches of linguistics concerned with meaning. These subfields have traditionally been divided according to aspects of meaning: "semantics" refers to grammatical and lexical meanings, while "pragmatics" is concerned with meaning in context. Within linguistics, the subfield of formal semantics studies the denotations of sentences and how they are composed from the meanings of their constituent expressions. Formal semantics draws heavily on philosophy of language and uses formal tools from logic and computer science. On the other hand, cognitive semantics explains linguistic meaning via aspects of general cognition, drawing on ideas from cognitive science such as prototype theory.
Pragmatics focuses on phenomena such as speech acts, implicature, and talk in interaction.[25] 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 the structural and linguistic knowledge (grammar, lexicon, etc.) of the speaker and listener, but also on the context of the utterance,[26] any pre-existing knowledge about those involved, the inferred intent of the speaker, and other factors.[27]
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, and it tells us what sounds are in a language, how they do and can combine into words, and explains why certain phonetic features are important to identifying a word.[28]
Linguistic structures are pairings of meaning and form. Any particular pairing of meaning and form is a Saussurean linguistic 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.
