Etymology
It is inherited from Proto-West Germanic *munþ, from Proto-Germanic *munþaz (“mouth”).[1][2] The Proto-Germanic noun is continued in Gothic 𐌼𐌿𐌽𐌸𐍃 (munþs), Old Norse munnr beside muðr, Old Frisian mūth, Old Saxon mūth and Old High German mund.[2][3]
Kroonen and Orel reconstruct Proto-Indo-European *mn̥t-o- and compare Latin mentum (“chin”) and Middle Welsh mant (“jaw, gums”);[2][4] Kroonen also considers a root *stment-.[2][4] Köbler gives the root *ment- (“to chew; mouth”).[5]
The nasal was lost before the fricative ⟨þ⟩ and the vowel lengthened, a change Old English shares with Old Frisian and Old Saxon: Proto-Germanic ⟨*munþaz⟩ became ⟨*mų̄þ⟩ and then ⟨mūþ⟩, against the ⟨nd⟩ of Old High German.[6][7]
Earliest recorded meaning
The word is recorded from the mid-ninth century: the Vespasian Psalter gloss has Ðes muð awergednisse & bitternisse ful is & facne “whose mouth is full of cursing and bitterness and deceit” over the Latin “Cuius os maledictione et amaritudine plenum est, et dolo” of Psalm 9.[8][9]
Semantic evolution
The word names the mouth as the way in for food, as the organ of speech and, in phrases such as mūþe tō mūþe, the face.[10][11] It also means any opening: Bosworth and Toller cite the gloss orificium, and the gnomic verses ask for rum recedes muþ, a roomy door, on a hall.[10] In glosses it renders Latin os, labium and ostium.[5] Æthelberht's laws use it of the mouth, Alfred's of the opening of a wound.[12] The MED traces Middle English mouth to this word and to mūþa “mouth of a river”.[13]
