Did You Know?
Superannuated was first put to use in English in the 1600s, having been borrowed from Medieval Latin superannuatus, the past participle of "superannuari" ("to be too old") - from Latin super- ("over" or "above") and "annus" ("year"). Shortly thereafter, we made our own verb, "superannuate," from the adjective. Superannuate meant "to retire and pension because of age or infirmity as well as "to declare obsolete," meanings that are still in active service. "Superannuated" can mean "outmoded or old-fashioned," as in "superannuated slang" or "superannuated neckties," or it can simply mean "older than usual," as in our example sentence.
