Colorless green ideas sleep furiously

Colorless green ideas sleep furiously" is a sentence composed by Noam Chomsky in his 1957 Syntactic Structures as an example of a sentence that is grammatically correct (logical form) but semantically nonsensical.
The term was originally used in his 1955 thesis "Logical Structures of Linguistic Theory".

Although the sentence is grammatically correct, no understandable meaning can be derived from it, and thus it demonstrates the distinction between syntax and semantics
