Word Origin and History for extra

1650s as a stand-alone adjective; also used as an adverb and noun in 17c. (see extra-); modern usages -- including sense of "minor performer in a play" (1777) and "special edition of a newspaper" (1793) -- all probably are from shortenings of extraordinary, which was used extensively in 18c. as noun and adverb in places we would use extra today.


only recorded in classical Latin in extraordinarius, but much used in Medieval Latin and modern formations; it represents Latin extra (adv.) "on the outside, without, except," the old fem. ablative singular of exterus "outward, outside," comparative of ex "out of" (see ex-).
