ABSTRACT
There is a redundancy in theory that I think Minimalists have overlooked. In syntactic derivation a structure is built up which is a perfect mirror of the derivation itself: every Merge is recorded in that structure, and every Move. It is only after the syntactic derivation that rules of Morphosyntax (and possibly stylistic rules) muddy the perfect mirror of derivation in structure. This structure should be eliminated on Minimalist grounds. But given that it serves as the input to Morphosyntax and also to semantics (two different interfaces, if you like) the question of its existence seems off the table.
