Did You Know?

Who needs homologate? We have any number of words that mean "to officially approve something": accredit, affirm, approbate, authorize, certify, confirm, endorse, ratify, sanction, warrant, and validate, for example. Homologate, which has been around more than 400 years, has mostly been kept for special occasions; Scottish Law, for example, held that "a marriage contract, though defective in the legal solemnities, is held . . . to be homologated by the subsequent marriage of the parties." The beauty of homologate is that, etymologically speaking, it's an easy word, consisting as it does of the familiar Greek roots homos, meaning "alike" or "same," and logos, meaning "word" or "speech"-in other words, "saying the same thing," thus, "agreeing." So we need not agree with the Scottish bishop who in 1715 called it a "hard word."
