This book, now in its third edition, is still the most uniquely comprehensive resource for finding word parts needed to express a concept. Along with aiding vocabulary expansion, this dictionary provides guidance to those who may be interested in inventing or deciphering words bearing an established and embedded meaning. Like prior editions, this work is split into three parts. Part I, the dictionary proper, provides an alphabetical listing of over 5,100 word parts. Each entry includes a brief definition, examples of use and etymology. Part II, the Finder, is a reverse dictionary that allows users to start with a meaning or concept to then find word parts which express that meaning. Still the only reverse dictionary of its kind, Part II is updated with over 4,600 search terms in total. Lastly, the expanded Part III organizes word parts under twenty convenient and summative categories-- like Body Parts, Experts and Shapes.
