A Context-Sensitive Grammar is a Grammar Class that allows Production Rules whose left hand side can depend on a context of Terminal Symbols.
- AKA: Context Sensitive Grammar.

- It can be used to Model a Natural Language Syntax, such as Swiss-German and Bambara.
- It can be a Mildly Context-Sensitive Grammar.
- It can generate a Context-Sensitive Language.

- A context-sensitive grammar (CSG) is a formal grammar in which the left-hand sides and right-hand sides of any production rules may be surrounded by a context of terminal and nonterminal symbols. Context-sensitive grammars are more general than context-free grammars but still orderly enough to be parsed by a linear bounded automaton.
- The concept of context-sensitive grammar was introduced by Noam Chomsky in the 1950s as a way to describe the syntax of natural language where it is indeed often the case that a word may or may not be appropriate in a certain place depending upon the context. A formal language that can be described by a context-sensitive grammar is called a context-sensitive language.
