mid-14c., enginour, "constructor of military engines," from Old French engigneor "engineer, architect, maker of war-engines; schemer" (12c.), from Late Latin ingeniare (see engine); general sense of "inventor, designer" is recorded from early 15c.; civil sense, in reference to public works, is recorded from c. 1600 but not the common meaning of the word until 19c (hence lingering distinction as civil engineer). Meaning "locomotive driver" is first attested 1832, American English. A "maker of engines" in ancient Greece was a mekhanopoios.[engineer etymology, engineer origin, 英语词源]
hanker (v.)youdaoicibaDictYouDict
c. 1600, "linger in expectation;" 1640s, "have a longing or craving for," of unknown origin. Probably from Flemish hankeren, related to Dutch hunkeren "to hanker, to long for," which is perhaps an intensive or frequentative of Middle Dutch hangen "to hang" (see hang (v.)). If so, the notion is of "lingering about" with longing or craving. Compare English hang (v.) in hang on (someone's) every word. Related: Hankered; hankering.
linger (v.)youdaoicibaDictYouDict
c. 1300, lenger "reside, dwell," northern England frequentative of lengen "to tarry," from Old English lengan "prolong, lengthen," from Proto-Germanic *langjan "to make long" (cognates: Old Frisian lendza, Old High German lengan, Dutch lengen "to lengthen"), source of Old English lang (see long (adj.)). Sense of "delay going, depart slowly and unwillingly" is from 1520s. Related: Lingered; lingering.
malinger (v.)youdaoicibaDictYouDict
1820, from French malingrer "to suffer," perhaps also "pretend to be ill," from malingre "ailing, sickly" (13c.), of uncertain origin, possibly a blend of mingre "sickly, miserable" and malade "ill." Mingre is itself a blend of maigre "meager" + haingre "sick, haggard," possibly from Germanic (compare Middle High German hager "thin"). The sense evolution may be through notion of beggars with sham sores. Related: Malingered; malingering; malingerer (1785).
