Grammar

In grammar, a conjunction (abbreviated CONJ or CNJ) is a part of speech that connects words, sentences, phrases, or clauses.

In formal language theory, a grammar (when the context is not given, often called a formal grammar for clarity) is a set of production rules for strings in a formal language.

In linguistics, grammar is the set of structural rules governing the composition of clauses, phrases, and words in any given natural language.

A noun (from Latin nōmen, literally meaning "name") is a word that functions as the name of some specific thing or set of things, such as living creatures, objects, places, actions, qualities, states of existence, or ideas.

(This article is about the part of speech. For the publishing platform, see Pronoun (publishing platform).) In linguistics and grammar, a pronoun (abbreviated PRO) is a word that substitutes for a noun or noun phrase.

Reduplication in linguistics is a morphological process in which the root or stem of a word (or part of it) or even the whole word is repeated exactly or with a slight change.

Semantics (from Ancient Greek: σημαντικός sēmantikos, "significant") is primarily the linguistic, and also philosophical study of meaning—in language, programming languages, formal logics, and semiotics.

Generative grammar is a linguistic theory that considers grammar to be a system of rules that is intended to generate exactly those combinations of words which form grammatical sentences in a given language.

A question is a linguistic expression used to make a request for information, or the request made using such an expression.

In traditional grammar, a solecism is a phrase that transgresses the rules of grammar.

In grammar, a supine is a form of verbal noun used in some languages.

In language learning, the principal parts of a verb are those forms that a student must memorize in order to be able to conjugate the verb through all its forms.

National Grammar Day is observed in the United States on March 4.

Constraint-based grammars can perhaps be best understood in contrast to generative grammars.
