Paul Martin Postal (born November 10, 1936, in Weehawken, New Jersey) is an American linguist.
Postal received his PhD from Yale University in 1963 and taught at MIT until 1965.
An important figure in the early development of generative grammar, he became a proponent of the generative semantics movement along with George Lakoff, James D. McCawley, and Haj Ross.
Later, with David E. Johnson, he developed Arc Pair Grammar.
These non-transformational theories of grammar have had an indirect but major impact on modern syntactic analysis.
