Abstract
This paper attempts to make clear that there are two distinct types of adjuncts, which we call central and peripheral adjuncts. This proposal leads us to claim that there are three distinct levels of verb phrases, with one level for (adverbial) complements being added, and we call these three levels V1, V2, and V3.
Furthermore, we point out that the two-level hypothesis for VP generally assumed in the recent framework of X-bar theory fails to capture in a consistent and convincing manner the differences which we observe in this paper.
