10 Mar context-free
A finite set of symbols or variables which represent categories applied to lexical elements (terminals). Context-free grammar (CFG) is great for defining relationships between syntactic objects as exemplified by the syntax of a programming language. A CFG has a start or goal symbol, terminal symbols which represent instances of variables, and production rules which combine to eventually derive the goal.
