摘要: This paper aims to provide a logical background for Combinatory Categorial Grammar (CCG) and its typological discussions. Based on the Curry-Howard correspondence between Gentzen-style proof systems Lambek Lamda Calculi, those Hilbert-style substructural BCWK-logic, I define new class of logic which provides subclasses each combinatory logics, called Subdirectional Logic, propose that CCG is subdirectional relevance (Combinatory Hypothesis). hypothesis allows us discuss parameters in universal grammar terms presence/absence certain directional combinators.
