Pronunciation

  • IPA: UK /ˈwɔː.nɪŋ/, US /ˈwɔːr.nɪŋ/[1]

Etymology

It is inherited from Old English warnung, war(e)nung,[2][3][4] the verbal noun of warnian, the source of warn, formed with -ung, the source of -ing.[2][3]

Earliest recorded meaning

Previous notice or threat of coming evil or danger: before 800 in the OED.[5] Taking heed, precaution, is from about 1000, now obsolete.[5][4]

Semantic evolution

Deterrent counsel, advice against an unwise course, is also from about 1000,[5] and advice to beware of a dangerous person or thing from before 1225.[5] A sign or portent of coming evil is from about 1325,[5] the early 14th century in Etymonline,[2] and a person or experience that deters by example later, from 1613 in the OED.[2][5] To take warning is from 1550.[5] The adjective, “that warns”, is from 1511 in Merriam-Webster[3] and 1552 in the OED,[5] as in warning coloration in zoology.[4] A siren signal before an air raid is from 1917,[2] and the police caution given on arrest from 1919.[5] Johnson in 1755 defined it as “caution against faults or dangers; previous notice of ill”.[6]
