Particles are an essential component of the Japanese language, and a facility with their use is essential for a mastery of both spoken and written forms. This new workbook will help students acquire that facility. It introduces 60 particles and their 188 basic functions in order of frequency of usage. Each function is illustrated with example sentences, and exercises are presented every few lessons to allow users to test their understanding, writing directly in the workbook and checking their work against the answers provided. A basic vocabulary is employed throughout to allow students to concentrate fully on one important goal—the mastery of Japanese particles.
