- worry (v.)
- 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.
- worry (n.)
- "anxiety arising from cares and troubles," 1804, from worry (v.).
