Context-free grammar
In formal language theory, a context-free grammar is a formal grammar in which every production rule is of the form where V is a single nonterminal symbol, and w is a string of terminals and/or nonterminals. A formal grammar is considered "context free" when its production rules can be applied regardless of the context of a nonterminal. It does not matter which symbols the nonterminal is surrounded by, the single nonterminal on the left hand side can always be replaced by the right hand side. The languages generated by context-free grammars are known as the context-free languages. Context-free grammars are important in linguistics for describing the structure of sentences and words in natural language, and in computer science for describing the structure of programming languages and other formal languages. In linguistics, some authors use the term phrase structure grammar to refer to context-free grammars, whereby phrase structure grammars are distinct from dependency grammars. In computer science, a popular notation for context-free grammars is Backus–Naur Form, or BNF.
