Word Origin and History for mouthed



Old English muþ "mouth, opening, door, gate," from Proto-Germanic *munthaz (cf. Old Saxon, Old Frisian muth, Old Norse munnr, Danish mund, Middle Dutch mont, Dutch mond, Old High German mund, German Mund, Gothic munþs "mouth"), with characteristic loss of nasal consonant in Old English (cf. tooth, goose, etc.), from PIE *mnto-s (cf.

Mouth-organ attested from 1660s.



c.1300, "to speak," from mouth (n.). Related: Mouthed; mouthing. Old English had muðettan "to blab."
