plagiarism (n.)[plagiarism 词源字典]: 1620s, from -ism + plagiary (n.) "plagiarist, literary thief" (1590s), from Latin plagiarius "kidnapper, seducer, plunderer, one who kidnaps the child or slave of another," used by Martial in the sense of "literary thief," from plagiare "to kidnap," plagium "kidnapping," from plaga "snare, hunting net," perhaps from PIE *plag- (on notion of "something extended"), from root *plak- (1) "to be flat" (see placenta).[plagiarism etymology, plagiarism origin, 英语词源]
romancer (n.): mid-14c., "chronicler writing in French," from Old French romanceour, from romanz (see romance (n.)). Later, "one inclined to romantic imagination" (the main sense 19c.); modern use for "seducer, wooer" of a romantic quality appears to be a new formation c. 1967 from romance (v.).
Romeo (n.): "a lover, passionate admirer, seducer of women," 1766, from the name of the hero in Shakespeare's tragedy "Romeo and Juliet" (1590s).
seduce (v.): 1520s, "to persuade a vassal, etc., to desert his allegiance or service," from Latin seducere "lead away, lead astray," from se- "aside, away" (see secret (n.)) + ducere "to lead" (see duke (n.)). Sexual sense, now the prevailing one, is attested from 1550s and apparently was not in Latin. Originally "entice (a woman) to a surrender of chastity." Related: Seduced; seducing.

Replaced Middle English seduisen (late 15c.), from Middle French séduire "seduce," from Old French suduire "to corrupt, seduce," from Latin subducere "draw away, withdraw, remove" (see subduce).
seductible (adj.): 1620s, from seduct-, past participle stem of Latin seducere (see seduce) + -ible. Related: Seductibly; seductibility.
seduction (n.): 1520s, from Middle French séduction, from Latin seductionem (nominative seductio), noun of action from past participle stem of seducere (see seduce). Originally with reference to actions or beliefs; sexual sense is from 1769, originally always with women as the objects. Earlier appearance of the word in Middle English with a sense "treason, treachery" probably is a confusion with sedition, which confusion also is found in Old French seducion "treason, betrayal."
seductive (adj.): 1740, from Latin seduct-, past participle stem of seducere (see seduce) + -ive. Related: Seductively; seductiveness. Middle English had seducious "deceitful, devious" (mid-15c.).
seductress (n.): 1803, "female seducer," with -ess + obsolete seductor (late 15c., displaced by seducer), from a direct borrowing of the Latin agent noun of seducere (see seduce).
