アルコール

If アルコール looks like English alcohol with Japanese vowels, surprise: the older Japanese science story points strongly through Dutch. Dictionaries often mark the source as Dutch alcohol, sometimes alongside English, because the modern European forms look so similar. The deeper passport is even older. European alcohol goes back through medieval scholarly vocabulary to Arabic al-kuhl, originally connected with a fine powder used around the eyes. Over time the word’s meaning shifted through ideas of refined essence and distilled substance until it became the chemical and drink word recognized across many languages. That makes アルコール a good 蘭学-style science word. Japan needed terms for chemistry, medicine, fermentation, disinfection, and physiology. Dutch learning helped carry many such words into Japanese before English became the default foreign language for science and business. アルコール belongs naturally beside older technical words like レンズ and スポイト. Modern Japanese uses it in several layers. アルコール can mean alcohol as a chemical class, ethanol in particular, disinfecting alcohol, or alcoholic drinks. アルコール消毒 feels medical and practical. アルコールに弱い means someone does not handle drinking well. アルコール飲料 is formal; in ordinary talk, 酒 or お酒 may be more natural for drinks. The learner lesson is simple but important. The meaning overlaps with English, but the Japanese word is not just a recent copy of English “alcohol.” It is a chemical word with Arabic roots, European science clothing, and a Dutch route into Japanese. A bottle of sanitizer can carry a long dictionary journey.
