Structures

This grammar of English embraces major lexical, phonological, syntactic structures and interfaces. It is based on the substantive assumption: that the categories and structures at all levels represent mental substance, conceptual and/or perceptual. The adequacy of this assumption in expressing linguistic generalizations is tested. The lexicon is seen as central to the grammar; it contains signs with conceptual, or content, poles, minimally words, and perceptual, and expression, poles, segments.
