1630s, “obsolete, out of date;”

1740, “retired on account of old age,” from Modern Latin superannuatus, alteration (perhaps by influence of annual) of Medieval Latin superannatus (which meant “more than a year old” and was used of cattle), from Latin super “beyond, over” (see super-) + annus “year” (see annual (adj.)). Earlier in same sense was superannate (c. 1600), from Medieval Latin superannatus. Compare French suranner

A very interesting problem arises when comparing “superannuate,” with “superannate.”
