Word History: Though colorless itself, slivovitz is made from bluish plums, and the name for this kind of brandy or schnapps is of Slavic origin and ultimately comes from the Indo-European root meaning "blue." The Slavic words for "plum," such as Serbo-Croatian šljiva, Czech slíva, and Russian sliva, are related to Latin līvidus, "bluish, bruise-colored," from which we get livid, a word synonymous with our black-and-blue when used to describe the discoloration caused by a bruise. The Indo-European root *sleiə-, "bluish," from which the Slavic and the Latin words are descended, has another descendant in English associated with alcohol, sloe, the name of a small sour plum of a dark purplish color. Many who have never seen this type of plum have tasted it in sloe gin, which is flavored with sloes.
