A bilingual dictionary compiling cant, slang, and colorful colloquialisms from modern French speech, presented alphabetically with English equivalents and illustrative quotations; it includes a preface on the compiler’s method and sources, notes on variant spellings and editorial choices, and selective etymological comments. Entries record usages from literature, journalism, and oral informants, with occasional archaic or eccentric terms retained for completeness. The work aims to help English readers interpret vernacular language found in contemporary fiction and social reportage, and it cites authorities and examples to clarify meanings while limiting extensive historical derivations.
