[Medieval Latin, fine metallic powder, especially of antimony, from Arabic al-kuḥl : al-, the + kuḥl, powder of antimony; see kḥl.]
Word History: The al- in alcohol may alert some readers to the fact that this is a word of Arabic descent, as is the case with algebra and alkali, al- being the Arabic definite article corresponding to the in English. The second part of the word, -cohol, comes from Arabic kuḥl, the word for a fine powder (most often made from antimony) used as a cosmetic to darken the eyelids. In fact, kuḥl has given us the word kohl for such a preparation. The Arabic phrase al-kuḥ, "the kohl," was borrowed into Medieval Latin as one word, alcohol, "koḥl." From Medieval Latin it was borrowed into English in the 16th century. In English, alcohol came to refer to any fine powder produced in a number of ways, as by heating a substance to a gaseous state and then cooling it. Alcohol could also be used to refer to essences obtained by distillation. One of these distilled essences produced by alchemists and early chemists, known as alcohol of wine, was the constituent of fermented liquors that causes intoxication, and the term alcohol came to refer to this essence (what modern chemists would call ethanol) in particular. Eventually, the liquors that contained this essence began to be called alcohol, too. In the terminology of modern chemistry, alcohol has also come to refer to the class of compounds to which ethanol belongs.
