Linguistics

Benjamin Atwood Lee Whorf (/hwɔːrf/; April 24, 1897 – July 26, 1941) was an American linguist and fire prevention engineer best known for proposing the Sapir–Whorf hypothesis. He believed that the structures of different languages shape how their speakers perceive and conceptualize the world. Whorf saw this idea, named after him and his mentor Edward Sapir, as having implications similar to those of Einstein's principle of physical relativity. However, the concept originated from 19th-century philosophy and thinkers like Wilhelm von Humboldt and Wilhelm Wundt.

Whorf initially pursued chemical engineering but developed an interest in linguistics, particularly Biblical Hebrew and indigenous Mesoamerican languages. His groundbreaking work on the Nahuatl language earned him recognition, and he received a grant to study it further in Mexico. He presented influential papers on Nahuatl upon his return. Whorf later studied linguistics with Edward Sapir at Yale University while working as a fire prevention engineer.

Louis Trolle Hjelmslev (Danish: [ˈjelˀmsle̝w]; 3 October 1899 – 30 May 1965) was a Danish linguist whose ideas formed the basis of the Copenhagen School of linguistics. Born into an academic family (his father was the mathematician Johannes Hjelmslev), Hjelmslev studied comparative linguistics in Copenhagen, Prague and Paris (with Antoine Meillet and Joseph Vendryes, among others). In 1931, he founded the Cercle Linguistique de Copenhague. Together with Hans Jørgen Uldall he developed a structuralist theory of language which he called glossematics, which further developed the semiotic theory of Ferdinand de Saussure. Glossematics as a theory of language is characterized by a high degree of formalism. It is interested in describing the formal and semantic characteristics of language in separation from sociology, psychology or neurobiology, and has a high degree of logical rigour. Hjelmslev regarded linguistics – or glossematics – as a formal science. He was a pioneer of formal linguistics. Hjelmslev's theory became widely influential in structural and functional grammar, and in semiotics.

Michael Alexander Kirkwood Halliday (often M. A. K. Halliday; 13 April 1925 – 15 April 2018) was a British linguist who developed the internationally influential systemic functional linguistics (SFL) model of language. His grammatical descriptions go by the name of systemic functional grammar. Halliday described language as a semiotic system, "not in the sense of a system of signs, but a systemic resource for meaning". For Halliday, language was a "meaning potential"; by extension, he defined linguistics as the study of "how people exchange meanings by 'languaging'". Halliday described himself as a generalist, meaning that he tried "to look at language from every possible vantage point", and has described his work as "wander[ing] the highways and byways of language". But he said that "to the extent that I favoured any one angle, it was the social: language as the creature and creator of human society".

Halliday's grammar differs markedly from traditional accounts that emphasise the classification of individual words (e.g. noun, verb, pronoun, preposition) in formal, written sentences in a restricted number of "valued" varieties of English. Halliday's model conceives grammar explicitly as how meanings are coded into wordings, in both spoken and written modes in all varieties and registers of a language. Three strands of grammar operate simultaneously. They concern (i) the interpersonal exchange between speaker and listener, and writer and reader; (ii) representation of our outer and inner worlds; and (iii) the wording of these meanings in cohesive spoken and written texts, from within the clause up to whole texts. Notably, the grammar embraces intonation in spoken language. Halliday's seminal Introduction to Functional Grammar (first edition, 1985) spawned a new research discipline and related pedagogical approaches. By far the most progress has been made in English, but the international growth of communities of SFL scholars has led to the adaptation of Halliday's advances to some other languages.

In linguistics, linguistic competence is the system of unconscious knowledge that one has when one knows a language. It is distinguished from linguistic performance, which includes all other factors that allow one to use language in practice.

In approaches to linguistics which adopt this distinction, competence would normally be considered responsible for the fact that "I like ice cream" is a possible sentence of English, the particular proposition that it denotes, and the particular sequence of phones that it consists of. Performance, on the other hand, would be responsible for the real-time processing required to produce or comprehend it, for the particular role it plays in a discourse, and for the particular sound wave one might produce while uttering it.

Sociolinguistics is the descriptive, scientific study of how language is shaped by, and used differently within, any given society. The field largely looks at how a language varies between distinct social groups and under the influence of assorted cultural norms, expectations, and contexts, including how that variation plays a role in language change. Sociolinguistics combines the older field of dialectology with the social sciences in order to identify regional dialects, sociolects, ethnolects, and other sub-varieties and styles within a language.

A major branch of linguistics since the second half of the 20th century, sociolinguistics is closely related to and can partly overlap with pragmatics, linguistic anthropology, and sociology of language, the latter focusing on the effect of language back on society. Sociolinguistics' historical interrelation with anthropology can be observed in studies of how language varieties differ between groups separated by social variables (e.g., ethnicity, religion, status, gender, level of education, age, etc.) or geographical barriers (a mountain range, a desert, a river, etc.). Such studies also examine how such differences in usage and in beliefs about usage produce and reflect social or socioeconomic classes. As the usage of a language varies from place to place, language usage also varies among social classes, and some sociolinguists study these sociolects.

A phoneme (/ˈfoʊniːm/) is any set of similar speech sounds that are perceptually regarded by the speakers of a language as a single basic sound—a smallest possible phonetic unit—that helps distinguish one word from another. All languages contain phonemes (or the spatial-gestural equivalent in sign languages), and all spoken languages include both consonant and vowel phonemes. Phonemes are studied under phonology, a branch of the discipline of linguistics (a field encompassing language, writing, speech and related matters).

Phonemes are often represented, when written, as a glyph (a character) enclosed within two forward-sloping slashes /. So, for example, /k/ represents the phoneme or sound used in the beginning of the English language word cat (as opposed to, say, the /b/ of bat).

In linguistics, borrowing is a type of language change in which a language or dialect undergoes change as a result of contact with another language or dialect. In typical cases of borrowing, speakers of one language (the "recipient" language) adopt into their own speech a novel linguistic feature that they were exposed to due to its presence in a different language (the "source" or "donor" language).

Linguistic prescription is the establishment of rules defining publicly preferred usage of language, including rules of spelling, pronunciation, vocabulary, grammar, etc. Linguistic prescriptivism may aim to establish a standard language, teach what a particular society or sector of a society perceives as a correct or proper form, or advise on effective and stylistically apt communication. If usage preferences are conservative, prescription might appear resistant to language change; if radical, it may produce neologisms. Such prescriptions may be motivated by consistency (making a language simpler or more logical); rhetorical effectiveness; tradition; aesthetics or personal preferences; linguistic purism or nationalism (i.e. removing foreign influences); or to avoid causing offense (etiquette or political correctness).

Prescriptive approaches to language are often contrasted with the descriptive approach of academic linguistics, which observes and records how language is actually used (while avoiding passing judgment). The basis of linguistic research is text (corpus) analysis and field study, both of which are descriptive activities. Description may also include researchers' observations of their own language usage. In the Eastern European linguistic tradition, the discipline dealing with standard language cultivation and prescription is known as "language culture" or "speech culture".

A grammar book is a book or treatise describing the grammar of one or more languages. In linguistics, such a book is itself frequently referred to as a grammar.

In linguistics, a grammatical construction is any syntactic string of words ranging from sentences over phrasal structures to certain complex lexemes, such as phrasal verbs.

Grammatical constructions form the primary unit of study in construction grammar theories. In construction grammar, cognitive grammar, and cognitive linguistics, a grammatical construction is a syntactic template that is paired with conventionalized semantic and pragmatic content. In generative frameworks, constructions are generally treated as epiphenomenal, being derived by the general syntactic rules of the language in question.
