The word "alcohol" traces back to Arabic al-kuḥl, originally referring to kohl, a fine powder used as eyeliner. Medieval Latin adopted alcohol to denote any refined substance, later narrowing to distilled liquids. By the 16th century, it specifically described the intoxicating essence of fermented drinks, reflecting its chemical refinement process. The term’s evolution mirrors the cultural exchange of scientific knowledge between Arabic and European traditions.
