pre-eminence (n.)

early 15c., "standing or rising above other places; exceeding other things in quality or degree;" from Old French éminent "prominent" (13c.) or directly from Latin eminentem (nominative eminens) "standing out, projecting, prominent, high," figuratively "distinguished, distinctive," present participle of eminere "stand out, project; be prominent, be conspicuous," from assimilated form of ex "out" (see ex-) + -minere, which is related to mons "hill" (from PIE root *men- (2) "to project"). From 1610s, of persons, "distinguished in character or attainments." Related: Eminently.

also preeminent, early 15c., "superior, distinguished beyond others, eminent above others," from Old French preeminent and directly from Medieval Latin preeminentem, from Latin praeeminentem (nominative praeeminens), present participle of praeeminare "to transcend, excel," literally "to project forward, rise above" (see pre-eminence). Related: Pre-eminently; preeminently.

word-forming element meaning "before," from Old French pre- and Medieval Latin pre-, both from Latin prae (adverb and preposition) "before in time or place," from PIE *peri- (source also of Oscan prai, Umbrian pre, Sanskrit pare "thereupon," Greek parai "at," Gaulish are- "at, before," Lithuanian prie "at," Old Church Slavonic pri "at," Gothic faura, Old English fore "before"), extended form of root *per- (1) "forward," hence "beyond, in front of, before."

The Latin word was active in forming verbs. Also see prae-. Sometimes in Middle English muddled with words in pro- or per-.
