From Middle English or Old French alcohol (modern French alcool), from Arabic الكحل (al-kuħl, "kohl") (by broadening). The etymology is conventionally given as الكحل (al-kuħl), dating to 1672, and has been promulgated by such authorities as Webster's Third New International Dictionary, which traces it through Middle Latin and Old Spanish. It entered English (and other European languages) by an alchemical term, by etymological broadening thence broadening to any distillates, thence narrowing to ethanol specifically.
