Noam Chomsky – Syntactic Structures. Janua Linguarum, Nr. IV. The Hague: Mouton & Co., 1957
Chomsky’s first book, published only two years after he got his PhD. Hugely important in 20th-century linguistics, it contains the celebrated example of an utterance that is semantically meaningless while being syntactically correct – “Colorless green ideas sleep furiously”(p. 15).
