In semiotics, linguistics, sociology and anthropology, context refers to those objects or entities which surround a focal event, in these disciplines typically a communicative event, of some kind. Context is "a frame that surrounds the event and provides resources for its appropriate interpretation".
The set of all context-free languages is identical to the set of languages accepted by pushdown automata, which makes these languages amenable to parsing.Further, for a given CFG, there is a direct way to produce a pushdown automaton for the grammar (and thereby the corresponding language), though going the other way (producing a grammar given an automaton) is not as direct.
Context may refer to: Context (linguistics) , the relevant constraints of the communicative situation that influence language use, language variation, and discourse summary Computing

The complement of a context-sensitive language is itself context-sensitive [10] a result known as the Immerman–Szelepcsényi theorem. Membership of a string in a language defined by an arbitrary context-sensitive grammar, or by an arbitrary deterministic context-sensitive grammar, is a PSPACE-complete problem.
Context-free languages—or rather its subset of deterministic context-free languages—are the theoretical basis for the phrase structure of most programming languages, though their syntax also includes context-sensitive name resolution due to declarations and scope.
The pumping lemma for context-free languages (called just "the pumping lemma" for the rest of this article) describes a property that all context-free languages are guaranteed to have. The property is a property of all strings in the language that are of length at least p {\displaystyle p} , where p {\displaystyle p} is a constant—called the ...
Generalized, Hassan's findings reveal that language and context go hand in hand. Scholars have said that it is important to include culture studies into language studies because it aids in students' learning. The informational and situational context that culture provides helps language "make sense"; culture is a contextualization cue (Hassan ...
