Forms
mosca f (plural moscas)[1] The variant moxca spread widely in the 15th and 16th centuries, for example in the Celestina.[2][3]
Etymology
It is inherited from Latin musca (“fly”).[2][4][5][1] It has been in general use at every period and is common to all the Romance languages.[2] The same Latin word is Portuguese mosca, Galician mosca, Catalan mosca, Occitan mosca, French mouche, Italian mosca and Romanian muscă.[6][7][1]
De Vaan reconstructs Proto-Italic *muskā and Proto-Indo-European *mu-s-, perhaps an imitation of the humming of flies and gnats; the extension with -s- is shared by Latin, Greek, Balto-Slavic and Germanic.[8] Cognates are Ancient Greek μυῖα (muîa, “fly”), Lithuanian musė̃, Old Church Slavonic моуха (muxa), Old English mycg and Old High German mucka.[8][1] The English word midge belongs here.[1]
Earliest recorded meaning
Corominas finds the word first in a Mozarabic document of 1161, then in the Calila and in Juan Ruiz.[2][4] The earliest hit in the CDH is in the Semejanza del mundo (c. 1223), in a comparison: asi como la mosca quando esta enel rrodezno “just as the fly when it is on the millwheel”.[9]
Semantic evolution
Alfonso X's Lapidario prescribes crushed flies for a wasp sting.[10] Covarrubias (1611) gives the proverb Hazeos miel y comeros han moscas and says that a clinging person is called a mosca.[11] The Diccionario de Autoridades adds “money”, in a jocular style, with a quotation from Villaviciosa, and the bore called mosca de burro.[12][2] Moscas blancas “snowflakes” and moscas “sparks from a fire” are other old figurative uses.[2][6][5]
In the Canaries mosca de caballo is the horsefly, recorded from 1779.[13] In Chile mosca is also an abbreviated signature.[14] In sport it names the flyweight class in boxing, and in television the channel's logo in a corner of the screen.[1]
