musca

Etymology and origin of the Latin word musca

History

Pronunciation

  • IPA (Classical): [ˈmʊs.ka][1]
  • IPA (Ecclesiastical): [ˈmus.ka][1]

Forms

musca f (genitive muscae); first declension[1]

Etymology

It goes back to Proto-Italic *musko/ā-, from Proto-Indo-European *mu-s- (“fly, gnat”), quite possibly an imitative *mu for the humming of flies and mosquitoes.[2][1] The extension in *-s- is shared by Latin, Balto-Slavic, Greek and Germanic.[2]

Cognate with Ancient Greek μυῖα (muîa, “fly”), Old Armenian մուն (mun, “gnat”), Albanian mizë (“fly”), Lithuanian musė̃ (“fly”), Old Church Slavonic муха (muxa, “fly”) and Old English mycg (“midge”), the source of English midge.[2][3][1]

Earliest recorded meaning

It is found from Plautus onwards,[2][4] who uses it of prying people and unbidden guests.[5][6]

Semantic evolution

It meant a fly, and figuratively an inquisitive or importunate person, as in Plautus and in Cicero's anecdote puer, abige muscas “boy, drive away the flies”.[3][5][7] Suetonius tells that Domitian used to catch flies and stab them with a sharp stylus.[5][7] Seneca says of a dull man that he could not even stir up a fly.[7]

It survives as French mouche, Italian mosca and Romanian muscă,[1][8] and through Spanish mosquito “little fly” it gave English mosquito, and through French mousquette English musket.[9]

Timeline

  • c. 250–184 BC – Plautus uses it of meddlesome people.[3][4]
  • 116–27 BC – Varro uses it for the fly.[5][4]
  • 81–43 BC – Cicero reports the joke puer, abige muscas.[5][4]
  • c. 75–c. 150 AD – Suetonius tells of Domitian stabbing flies.[5][4]
  • 1580s – Spanish mosquito, its diminutive, enters English as English mosquito.[9]
