Etymology and origin of the French word mouche
From the same root
Pronunciation
- /muʃ/[1]
Forms
mouche f (plural mouches)[1] Old French musche, mosche (about 1120); mouche from the 13th century.[2][3][4] Anglo-Norman also moche and muske.[5] Dialect forms include Picard mouke and Walloon mohe.[6]
Etymology
It is inherited from Old French mosche, inherited from Latin musca (“fly; a curious, intrusive person”).[2][7][8][4][9][1] Rey explains the Latin noun as a diminutive with a ⟨-c-⟩ suffix of an Indo-European root, probably an imitation of buzzing, also seen in Ancient Greek μυῖα (muîa, “fly”) and Old Norse mý (“midge”).[7] Wiktionary gives the root as Proto-Indo-European *mus- (“fly”).[1]
Cognate with Italian mosca, Occitan mosca, Catalan mosca, Spanish mosca, Portuguese mosca and Romanian muscă.[10][11]
Earliest recorded meaning
It is first found about 1120 in the Oxford Psalter, as musche, for the fly, the two-winged insect.[2][7]
Semantic evolution
Until the 17th century the word also named many insects outside the fly family: the bee (1213), also called mouche à miel and still so called in Acadia, Louisiana and Guadeloupe, the wasp (mousches guespes, 1552) and the horsefly (mousche aus beufs, 1636).[2][7] Furetière still counted bumblebees, hornets and glow-worms among the mouches.[7] In Quebec mouche à feu is the firefly.[7][11]
Many phrases date from this wide use.[7] Prendre la mouche “to take offence” (1640) is the modern form of prendre mouskes (about 1350), and quelle mouche l'a piqué ? (1611) continues quel mouche le point ? (1485).[2][7] Fine handwriting was called pieds de mouche (1616) and later pattes de mouches (1798).[2] On prend plus de mouches avec le sucre qu'avec le vinaigre is recorded in 1718, on eût entendu voler une mouche in Stendhal (1836) and ne pas faire de mal à une mouche in Balzac (1844).[2][7] Faire la mouche du coche comes from La Fontaine's fable Le Coche et la Mouche.[8][11]
From the insect's quickness came fine mouche “a sharp, cunning person” (1486) and, in a bad sense, “spy” (1574, Amyot), the source of mouchard.[2][7][8] The word was also used for a small warship (1814) and a small steamboat (1867), whence bateau-mouche.[2][11] By likeness of shape or colour it named a patch of black taffeta worn on the face (1618), an artificial fly for fishing (1801), the black spot in the centre of a target (1834, Musset), whence faire mouche, and a tuft of hair below the lower lip (1840).[2][11]
