英语词汇apex的起源、历史背景-英语词源词典

词汇	apex
词源	apex n. "the tip, point, or summit" of anything, c. 1600, from Latin apex "summit, peak, tip, top, extreme end;" which is plausibly related to apere "to fasten, fix," hence "the tip of anything" (one of the meanings of apex in Latin was "small rod at the top of the flamen's cap"), and thus ultimately from PIE ap- (1) "to take, reach" (see apt). But if the original notion was "point," not "top," it might go another way. Proper plural is apices. Entries linking to apex* apt adj. mid-14c., "inclined, disposed;" late 14c., "suited, fitted, adapted, possessing the necessary qualities for the purpose," from Old French ate "fitting, suitable, appropriate" (13c., Modern French apte), or directly from Latin aptus "fit, suited, proper, appropriate," adjectival use of past participle of apere "to attach, join, tie to." This is reconstructed to be from PIE root ap- (1) "to grasp, take, reach" (source also of Sanskrit apnoti "he reaches," Latin apisci "to reach after, attain," Hittite epmi "I seize"). The elliptical sense of "becoming, appropriate" is from 1560s. apical adj. "of or belonging to an apex," 1827, from Latin apicem, from apex (see apex) + -al (1). updated on September 23, 2022
