prominent [prominent 词源字典]: prominent: [16] Prominent comes from the present participle of Latin prōminēre ‘jut out’. This was formed with the prefix prō- ‘forwards, out’ and -minēre ‘project’, a verbal element which also lies behind English eminent and imminent [16]. It was derived from *min- ‘project’, a base which also gave English menace and may be related ultimately to Latin mōns ‘mountain’ (source of English mount and mountain). Combination of prō- and mōns itself produced Latin prōmunturium ‘headland’, ancestor of English promontory [16].

promontory (n.): 1540s, from Middle French promontoire (15c.) and directly from Medieval Latin promontorium, altered (by influence of Latin mons "mount, hill") from Latin promunturium "mountain ridge, headland," probably related to prominere "jut out" (see prominent).
protrude (v.): 1610s, "to thrust forward or onward, to drive along;" 1640s, "to cause to stick out," from Latin protrudere "thrust forward; push out," from pro- "forward" (see pro-) + trudere "to thrust" (see extrusion).
