Word History

Etymology

borrowed from Medieval Latin contemporāneus, from Latin con- con- + tempor-, tempus "time" + -āneus, compound suffix formed from -ānus -an entry 2 + -eus -eous — more at -eous

Note: The Latin word contemporāneus occurs as a noun in the sense "contemporary" in a chapter heading of Aulus Gellius's Noctes Atticae (19.14), though these headings are most likely a post-classical interpolation. The word is otherwise not attested before the early Middle Ages.
