Context Free Grammar. Grammar defines a set of rules, and with the help of these rules valid sentences in a language are constructed. A grammar consists of collection of substitution rules, which are also called production rules. Context Free Grammar have recursive structure. The language that is associated with Context Free Grammar is called Context Free Language.

what is the context of an argumentative essay: how did the constitution guard against tyranny essay grabber ways In formal language theory, a context-free grammar (CFG) is a formal grammar whose production rules are of the form → with a single nonterminal symbol, and a string of terminals and/or nonterminals (can be empty). A formal grammar is "context free" if its production rules can be applied regardless of the context of a nonterminal. Definition − A context-free grammar (CFG) consisting of a finite set of grammar rules is a quadruple (N, T, P, S) where. N is a set of non-terminal symbols. T is a set of terminals where N ∩ T = NULL. P is a set of rules, P: N → (N ∪ T)*, i.e., the left-hand side of the production rule P does have any right context or left context.
