Jeongsil Song. 2001. Auxiliary Do. Studies in Modern Grammar 23, 75-93. This study discusses the distribution of the auxiliary do in the framework of the Minimalist Program. It is generally assumed that the auxiliary do appears in the context where Infl is not allowed to attach to a verbal element, that is, Infl is stranded. But how the context results doesn`t seem to have been clarified yet except a few typical cases such as negative and interrogative sentences. The auxiliary do also appear emphatic, imperative and VP-ellipsis sentences. Particularly in case of the imperative, the context seems quite difficult to describe. All the Infl-stranding contexts should be explained in the same manner. This study does that as follows. The emphatic sentence needs do when Aff, which is the emphatic morpheme appearing in the same position as not, blocks the covert raising of the main verb. The VP-ellipsis sentence needs do when the ellipsis leaves I stranded. The imperative needs do when negative or emphatic, regardless of auxiliary be or have appearing. This is because the auxiliary has some meaning and thus is not allowed to raise. The inverted ordering Don`t you - in the imperative is due to its lack of the EPP effect.
