A concise handbook that distills a larger multi-volume study into alphabetized entries defining Latin words, distinguishing closely related terms, and noting classical usage and opposites. It classifies synonyms into three pedagogical groups—those to learn early, those to teach at advanced stages, and those whose differences remain subtle—while omitting detailed etymologies and extended citations. Where useful, entries offer corresponding Greek or French equivalents and practical advice for teachers and students about when nuance matters in composition and textual interpretation.
