Etymology: The word is a plain technical coinage built in two steps. "Alkyl" was formed in English by combining "alc(ohol)" with "-yl", the suffix chemists used for radical groups, so the stem names a hydrocarbon fragment derived from alcohol. Its roots run back through Arabic "kuḥl", a word for a fine powder such as antimony used as eye cosmetic, which passed into medieval Latin as "alcohol" and then into English. "Alkylation" adds the suffix "-ation", the ordinary English ending for an action or process, taken through Old French from Latin "-ātiō". The result names the process of attaching an alkyl group to a molecule. Like many chemical terms, it was coined in modern times from older building blocks rather than used by any earlier writers.
