Pronunciation

  • Ecclesiastical: [ˈmuː.tus][1]

Forms

mūtus (feminine mūta, neuter mūtum); first/second-declension adjective[1]

Etymology

It is inherited from Proto-Italic *mūto-, inherited from Proto-Indo-European *mū̆-to-, from an imitative root: de Vaan explains it as one “who cannot say anything but ⟨mū⟩”.[2][3] Cognate with Sanskrit मूक (mū́ka-, “dumb”), Ancient Greek μυκός (mukós, “dumb”) and Old Armenian մունջ (munǰ, “dumb”).[2][4] Within Latin it is related to muttiō (“to mutter”) and mussō (“to murmur”).[2][3]

Earliest recorded meaning

Naevius, in a tragedy: dūcite eō … mūtās quadrupedīs, “lead the dumb four-footed beasts there”.[3][2][5]

Semantic evolution

It is first said of animals, which can only make inarticulate sounds, and as a neuter plural noun mūta are the dumb creatures.[3] Of people it is dumb, lacking speech (Plautus), and of things soundless; the dea Mūta was a nymph Jupiter struck dumb for talking too much (Ovid).[3] It often means simply silent, saying nothing, as Plautus' joke that no silent woman has ever been found, and a persōna mūta is a character who says nothing on stage.[3] With emotion it is speechless (Terence: he said nothing on the spot).[3]

Church Latin glosses it “dumb, unable to speak”, and as a noun a mute person.[6] In New Latin it is used as a specific epithet in biology.[1] English mute came through Old French muet in the late 14th century.[7]

Timeline

  • c. 235–200 BC – Naevius of dumb beasts.[3][5]
  • c. 250–184 BC – Plautus of dumb and silent people.[3][5]
  • 81–43 BC – Cicero of a silent character on the stage.[3][5]
  • late 14th century – English mute, through Old French.[7]
