Editing Generalized phrase structure grammar (section)

== Origins ==
GPSG was initially developed in the late 1970s by [[Gerald Gazdar]]. Other contributors include [[Ewan Klein]], [[Ivan Sag]], and [[Geoffrey Pullum]]. Their book ''Generalized Phrase Structure Grammar'', published in 1985, is the main monograph on GPSG, especially as it applies to English syntax. GPSG was in part a reaction against [[transformational grammar|transformational theories of syntax]]. In fact, the notational extensions to [[context-free grammars]] (CFGs) developed in GPSG are claimed to make transformations redundant.<ref>{{cite book | first=Gerald | last=Gazdar | author2=Ewan H.
