The Nature of Vocabulary Acquisition [PDF ebook] 

First published in 1987. The purpose of this volume has been to move beyond a collection of the most recent studies in the area of vocabulary learning. The contributors, and researchers who, although they may differ in their views on vocabulary acquisition and instruction, acknowledge that many of the same questions motivate their work. These questions and the way they have addressed have been included in order to emphasize these underlying commonalities, with the hope the relationships among contrasting perspectives will become more apparent.
