Word Origin and History for alcohol
1540s (early 15c. as alcofol), "fine powder produced by sublimation," from Medieval Latin alcohol "powdered ore of antimony," from Arabic al-kuhul "kohl," the fine metallic powder used to darken the eyelids, from kahala "to stain, paint." The al- is the Arabic definite article, "the."
"Powdered cosmetic" was the earliest sense in English; definition broadened 1670s to "any sublimated substance, the pure spirit of anything," including liquids. Modern sense of "intoxicating ingredient in strong liquor" is first recorded 1753, short for alcohol of wine, which was extended to "the intoxicating element in fermented liquors." In organic chemistry, the word was extended 1850 to the class of compounds of the same type as this.
