Brit.

/ᵻˈθʌɪnɪl/,

/ᵻˈθʌɪnʌɪl/,

/ˈɛθᵻnɪl/, U.S.

/ɛˈθaɪn(ə)l/,

/ˈɛθəˌnɪl/

Forms: 1800s– ethinyl, 1900s– ethynyl.

Origin: Formed within English, by derivation; perhaps modelled on a French lexical item, or perhaps modelled on a German lexical item. Etymons: ethyne n., -yl suffix.

Etymology: < ethyne n. (compare forms at that entry) + -yl suffix, after French éthinyle (1866) or its etymon German Aethinyl (A. W. Hofmann 1866, in Monatsbericht der Königl. Preuss. Akad. der Wissenschaften zu Berlin, 1865 653; now usually Ethynyl).

Chemistry.

The unsaturated hydrocarbon radical —C≡CH, derived from ethyne (acetylene). Usually attributive.See also ethinyloestradiol n.
