This study is impressive in its scope and thoroughness. The author clearly presents the issues in acquisition as well as in syntax. Accordingly, this study not only contributes original work to the field of L2 acquisition, but also attempts to use L2 data to support the claim that there is an aspect parameter that implicates telicity with resultatives, verb particles and double objects.

The main contribution of this volume is that it opens a new venue for the investigation of UG phenomena from the perspective of the L2 acquisition of telicity. Another strength of the volume is that the author acknowledges some of the faults of the study and methodology and provides alternative interpretations as well as suggestions for further research...the volume will be of great interest to researchers in syntax, semantics, and morphology in both L1 and L2 acquisition.
