Charlevoix is a proper noun, most commonly a French-origin surname and place name, used for a county and city in Quebec, Canada, and for other geographic or familial references. It entered English via French colonial and geographic usage, retaining its original French pronunciation for many speakers. In practice, English speakers often adapt the syllables to fit English phonotactics, producing a distinctive, multi-syllabic word with final-ioux-like ending.
