mosca f (plural mosques)[1]

Etymology

It is inherited from Latin musca (“fly”).[2][3][4][5][1]

The same Latin word is Occitan mosca, Spanish mosca, Portuguese mosca, Italian mosca, French mouche and Romanian muscă.[6][1][7]

The Latin word goes back to Proto-Indo-European *mus- (“fly”), with cognates in Ancient Greek μυῖα (muîa, “fly”), Old Church Slavonic моуха (muxa) and the English word midge.[8][1] De Vaan thinks it may imitate the humming of the insect.[8]

Earliest recorded meaning

Llull complains that people are troubled day and night by lice, fleas, bedbugs and flies (mosques) in the Llibre de contemplació.[9] Coromines quotes the epic passage of Desclot's chronicle on the siege of Girona in 1285, in which a plague of flies as big as acorns entered the nostrils of the horses and killed four thousand of them; this is the origin of the legend of the flies of Saint Narcissus.[2]

Semantic evolution

Labèrnia's dictionary of 1839 gives besides the insect the senses “spy” and the beauty spot of black taffeta worn on the face.[10] Martí Gadea adds in 1891 the tuft of hair under the lower lip, “money” and “an annoying person”.[11] Fabra's dictionary of 1932 records no faria mal a una mosca “he would not hurt a fly” and morir com a mosques “to die like flies”.[12] Mosca! is also an exclamation of surprise or admiration.[3][13]

Derivatives: moscalló (13th century), moscard (14th century, Eiximenis), mosquit “mosquito” (14th century), formed like cabrit from cabra, and moscarda (1575); mosquet “musket” (1598) was borrowed from Italian.[4]
