Abstract
This paper aims to discuss some treatments of the non-canonical ordering observed in the phenomenon known as Heavy NP Shift, and to show that HNPS is best analyzed as A'(rightward)-movement. Through discussion it will be shown that A'-movement analysis can provide natural explanations for some properties of HNPS. It will also be shown that an NP-Incorporation analysis proposed by Stowell (1981) may account for the impossibility of HNPS from the indirect object in the double object construction.
