Antisymmetry of Syntax

It is standardly assumed that Universal Grammar (UG) allows a given hierarchical representation to be associated with more than one linear order. For example, English and Japanese phrases consisting of a verb and its complement are thought of as symmetrical to one another, differing only in linear order. The Antisymmetry of Syntax proposes a restrictive theory of word order and phrase structure that denies this assumption. According to this theory, phrase structure always completely determines linear order, so that if two phrases differ in linear order, they must also differ in hierarchical structure.
