Meaning & origin
(measured from records)Le succès de l’opéra-comique Le petit Duc , de Meilhac et Halévy, en 1878, provoqua l’apparition argotique du mot duc pour désigner un chapeau melon à bords étroits. Le Dictionnaire de l’argot de Larousse signale aussi que l’expression « duc de Guiche » est employée pour désigner le directeur d’une prison, en jouant sur les mots Guise et guichet.

About this data
measured from records inferred from the name graph machine-generated
These figures come from the data snapshot of and will change as it is rebuilt.
Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.
Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
