The second type in this man's namesake hierarchy can be recognized by a non-deterministic pushdown automoton. He proposed an operation that yields alpha, alpha beta from alpha, beta, called merge, and the move alpha operator. His concept of the poverty of the stimulus holds that the degree to which young children are exposed to language is insufficient to alone account for language acquisition. He formulated the sentence "colorless green ideas sleep furiously" and developed the theory of generative grammar. For 10 points, name this author of Syntactic Structures and proponent of a universal grammar, a linguist at MIT.
