In linguistics, syntax (/ ˈ s ɪ n t æ k s / SIN-taks) [1] [2] 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, hierarchical sentence structure (constituency), [3] agreement, the nature of crosslinguistic variation, and the relationship between form and meaning ().
The syntax of grammars. In the classic formalization of generative grammars first proposed by Noam Chomsky in the 1950s, [2] [3] a grammar G consists of the following ...
A series of metastudies have found that the explicit teaching of grammatical parts of speech and syntax has little or no effect on the improvement of student writing quality in elementary school, middle school or high school; other methods of writing instruction had far greater positive effect, including strategy instruction, collaborative ...

The parts of speech are an important element of traditional grammars, since patterns of inflection and rules of syntax each depend on a word's part of speech. [12]Although systems vary somewhat, typically traditional grammars name eight parts of speech: nouns, pronouns, adjectives, verbs, adverbs, prepositions, conjunctions, and interjections.
Context-free grammars are a special form of Semi-Thue systems that in their general form date back to the work of Axel Thue. The formalism of context-free grammars was developed in the mid-1950s by Noam Chomsky, [3] and also their classification as a special type of formal grammar (which he called phrase-structure grammars). [4]
Thus, grammars that employ phrase structure rules are constituency grammars (= phrase structure grammars), as opposed to dependency grammars, [4] which view sentence structure as dependency-based. What this means is that for phrase structure rules to be applicable at all, one has to pursue a constituency-based understanding of sentence structure.
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.
