Bibulous describes someone given to drinking too much alcohol — a gently euphemistic adjective for habitual heavy drinking. The word’s Latin root means drinking, and it appears in literature and wry social commentary to describe characters fond of the bottle without the clinical bluntness of alcoholic. A bibulous evening suggests convivial excess; a bibulous lifestyle suggests a problem politely understated. The term’s charm is its understatement, allowing writers to signal concern while maintaining decorum. In modern health writing it has largely given way to precise measures of consumption and the language of alcohol use disorder, but bibulous survives where tone matters, a reminder that how we name drinking shapes how we judge it, and that euphemism itself can be a form of social commentary.
