中英词源

extra 额外的

ex-, 向外。-ter, 比较级后缀，见alternate.

extra: extra: [18] In its modern English use, ‘beyond what is normal’ or ‘additional’, extra is probably an abbreviation of extraordinary [15], in which the prefix represents Latin extrā ‘outside, beyond’. This in turn was short for exterā, the ablative feminine case of the adjective exterus ‘outer’ (from which English gets exterior [16]). And exterus itself began life as a compound form based on Latin ex ‘out’.
=> exterior, extreme
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) -- probably all are from shortenings of extraordinary, which in 18c. was used extensively as noun and adverb in places extra would serve today.
