Pronunciation

Forms

mosca f (plural mosche, diminutive moschétta or moschìna or moschìno m or moschettìna, augmentative (uncommon) moscóna, pejorative moscàccia)[1]

Etymology

It is inherited from Latin musca (“fly”).[2][3][4][1] The same word is French mouche, Occitan mosca, Catalan mosca, Spanish mosca, Portuguese mosca, Sardinian musca and Romanian muscă.[3][5]

DELI and Nocentini take the Latin noun as a diminutive of a widespread Proto-Indo-European *mus-, which is continued in Ancient Greek μυῖα (muîa), Lithuanian musė, Old Church Slavonic моуха (muxa), Old Norse mý and Albanian mizë.[2][3][6][1] Further cognates are Old High German mucka and English midge.[6][1] De Vaan thinks the base may imitate the humming of flies and mosquitoes, with an ⟨s⟩ extension in Latin, Balto-Slavic, Greek and Germanic.[6][7]

Earliest recorded meaning

The first record is in the Proverbia que dicuntur, a Venetian poem of the last quarter of the 12th century;[8][2] DELI dates the word to Iacopone da Todi, before 1306.[2] The sense is the insect.[8][2]

Semantic evolution

Old Italian used the fly for anything worthless and for the common people, and as an insult.[8] It had the mosca canina, a small biting fly, and the game mosca cieca, blind man's buff.[8][9] The augmentative moscone is in Dante (1300–1313), and Pietro Aretino used it for an insistent suitor in 1536 and mosca for a tiresome person in 1542.[2]

Later uses come from the look of the insect: the artificial beauty spot, the small tuft of beard under the lip (1803), the roasted coffee bean floated on sambuca and the artificial fly of anglers.[2][3][4] Navy usage named a fast dispatch vessel mosca (1813), and moscone became a beach pedal boat in 1923.[2] Mosca cocchiera, a busybody who fusses without being useful, translates La Fontaine's fable La mouche du coche and was the title of a polemical essay by Carducci (1896–1897).[2]

The diminutive moschetto gave the name of the musket, borrowed as French mousquet and Spanish mosquete.[5]

Usage notes

The interjection mosca! is Tuscan and central-southern;[15][16][9] DEI and Treccani explain it from non si sente volare una mosca, “you could hear a fly”, while Prati suggested a root imitating closed lips, reshaped after the insect's name.[15][16][9]

Common idioms are mosca bianca (a rare person), fare di una mosca un elefante (to make a mountain out of a molehill), non farebbe male a una mosca (he wouldn't hurt a fly) and restare con un pugno di mosche (to be left empty-handed).[11][10] Mosca with a capital is Moscow, from Russian Москва (Moskvá).[1]
