A historical and comparative dictionary of colloquial and heterodox speech, presenting alphabetically arranged entries (C–F) that define slang terms, trace etymologies, cite historical usages and quotations, and offer synonyms across English, French, German, Italian, and other languages. Entries combine lexical definitions with notes on register, obsolete senses, related cant terms, and illustrative citations from literature and periodicals; occasional essays discuss word formation and semantic change. The work serves as a linguistic reference to the social range and historical development of nonstandard vocabulary and idiom over several centuries.
