context-sensitive languages

Context-sensitive languages are a class of formal languages in computational theory that can be recognized by machines called linear-bounded automata. They are more expressive than context-free languages, allowing rules that depend on the context of a symbol’s surroundings. In practical terms, this means they can describe more complex patterns and structures, such as certain programming languages or natural language constructions, where the meaning or correctness depends on the context. These languages sit between context-free languages and recursively enumerable languages in complexity, balancing expressive power with decidability.
