In linguistics, focus (abbreviated FOC) is a grammatical category that conveys which part of the sentence contributes new, non-derivable, or contrastive information.In the English sentence "Mary only insulted BILL", focus is expressed prosodically by a pitch accent on "Bill" which identifies him as the only person Mary insulted. By contrast, in the sentence "Mary only INSULTED Bill", the …

Systemic functional grammar; Generative syntax. Generative syntax is the study of syntax within the overarching framework of generative grammar. Generative theories of syntax typically propose analyses of grammatical patterns using formal tools such as phrase structure grammars augmented with additional operations such as syntactic movement.

The first systematic grammar of Sanskrit, originated in Iron Age India, with Yaska (6th century BC), Pāṇini (6th–5th century BC) and his commentators Pingala (c. 200 BC), Katyayana, and Patanjali (2nd century BC). Tolkāppiyam, the earliest Tamil grammar, is mostly dated to before the 5th century AD. The Babylonians also made some early attempts at language description.

In statistical classification, two main approaches are called the generative approach and the discriminative approach. These compute classifiers by different approaches, differing in the degree of statistical modelling.Terminology is inconsistent, but three major types can be distinguished, following Jebara (2004): A generative model is a statistical model of the joint …

In grammar, a part of speech or part-of-speech (abbreviated as POS or PoS, also known as word class or grammatical category) is a category of words (or, more generally, of lexical items) that have similar grammatical properties. Words that are assigned to the same part of speech generally display similar syntactic behavior (they play similar roles within the grammatical …

In linguistics, morphology (/ m ɔːr ˈ f ɒ l ə dʒ i /) is the study of words, how they are formed, and their relationship to other words in the same language. It analyzes the structure of words and parts of words such as stems, root words, prefixes, and suffixes.Morphology also looks at parts of speech, intonation and stress, and the ways context can change a word's pronunciation and …

Universal grammar (UG), in modern linguistics, is the theory of the genetic component of the language faculty, usually credited to Noam Chomsky.The basic postulate of UG is that there are innate constraints on what the grammar of a possible human language could be. When linguistic stimuli are received in the course of language acquisition, children then adopt specific …

In traditional grammar. The grammatical relations are exemplified in traditional grammar by the notions of subject, direct object, and indirect object: . Fred gave Susan the book.. The subject Fred performs or is the source of the action. The direct object the book is acted upon by the subject, and the indirect object Susan receives the direct object or otherwise benefits from the …

Deep structure and surface structure (also D-structure and S-structure although those abbreviated forms are sometimes used with distinct meanings) are concepts used in linguistics, specifically in the study of syntax in the Chomskyan tradition of transformational generative grammar.. The deep structure of a linguistic expression is a theoretical construct that seeks to …

Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds or, for sign languages, their constituent parts of signs.The term can also refer specifically to the sound or sign system of a particular language variety.At one time, the study of phonology related only to the study of the systems of phonemes in spoken …

La grammaire générative et transformationnelle est une théorie syntaxique s’inscrivant dans le courant de la linguistique générative.Majoritairement présente en Amérique du Nord, elle s’est développée depuis 1957 sous l’impulsion de Noam Chomsky.Cette théorie tente de caractériser la connaissance de la langue qui permet l'acte effectif du locuteur-auditeur.

The term phrase structure grammar was originally introduced by Noam Chomsky as the term for grammar studied previously by Emil Post and Axel Thue (Post canonical systems).Some authors, however, reserve the term for more restricted grammars in the Chomsky hierarchy: context-sensitive grammars or context-free grammars.In a broader sense, phrase structure grammars …
