worryyoudaoicibaDictYouDict[worry 词源字典]
worry: [OE] Worry originally meant ‘strangle’. It comes from a prehistoric West Germanic *wurgjan, which also produced German wügen ‘choke, strangle’. The sense ‘harass physically’ (as in ‘dogs worrying sheep’) emerged in the 16th century, via an intermediate ‘seize by the throat’, and the modern sense ‘vex, disturb’ came on the scene in the 17th century, but the verb was not used intransitively until the mid- 19th century.
[worry etymology, worry origin, 英语词源]
worry (v.)youdaoicibaDictYouDict
Old English wyrgan "to strangle," from Proto-Germanic *wurgjan (cognates: Middle Dutch worghen, Dutch worgen, Old High German wurgen, German würgen "to strangle," Old Norse virgill "rope"), from PIE *wergh- "to turn" (see wring). Related: Worried; worrier; worrying.

The oldest sense was obsolete in English after c. 1600; meaning "annoy, bother, vex," first recorded 1670s, developed from that of "harass by rough or severe treatment" (1550s), as of dogs or wolves attacking sheep. Meaning "to cause mental distress or trouble" is attested from 1822; intransitive sense of "to feel anxiety or mental trouble" is first recorded 1860.
