Syntax

n. study of sentence structure (Grammar); rules governing the arrangement of instructions in a programming language (Computers); orderly arrangement

In computer science, SYNTAX is a system used to generate lexical and syntactic analyzers (parsers) (both deterministic and non-deterministic) for all kind of context-free grammars (CFGs) as well as some classes of contextual grammars. It is developed at INRIA (France) for several decades, mostly by Pierre Boullier, but has become free software since 2007 only. SYNTAX is distributed under the CeCILL licence.

“Syntactic” redirects here. For another meaning of the adjective, see Syntaxis In linguistics, syntax (from Ancient Greek συν- syn-, “together”, and τάξις táxis, “arrangement”) is the study of the rules that govern the structure of sentences, and which determine their relative grammaticality. The term syntax can also be used to refer to these rules themselves, as in “the syntax of a language”. Modern research in syntax attempts to describe languages in terms of such rules, and, for many practitioners, to find general rules that apply to all languages. Since the field of syntax attempts to explain grammaticality judgments, and not provide them, it is unconcerned with linguistic prescription.
