ABSTRACT=The goal of this article is to enhance the technical description of multi-lingual speakers in terms of a theory
of Multiple Grammars where more than one language utilizes a grammar.  The challenge of V2 and its
implications for interfaces from the perspective of the L2 learner is the focus.  A number of constructions
are considered including: Quotation, Topicaliation, Empty subjects and Objects, Expletives, and Subject-
auxiliary inversoni.
