Origin Story
The word alcohol comes from Arabic al-kuhl (الكحل), which originally meant a black powder ground finely from antimony ore. Since ancient Egypt, this powder had been used as eye cosmetic — kohl. Arab alchemists began applying al-kuhl to the process of repeatedly distilling a substance to extract its purest essence. That sense of "essence" widened until the clear liquid obtained by distilling wine — ethanol — came to be called the "alcohol of wine." In the 16th century Paracelsus introduced the term into chemistry, and by the 18th century alcohol had settled into its modern meaning: ethanol, and drink.
A great many scientific terms entered English from Arabic: algebra, algorithm, alchemy, almanac, and more. Most of them begin with al- — the Arabic definite article.

Memory Hook
alcohol = al (Arabic "the") + kohl (eye makeup). "The eye-makeup powder that became a drink!" Pure alchemical magic.
""For a powder once dusted on the eyes to slide down the throat, it first had to pass through an alchemist's still.""
