Pronunciation

  • IPA: /mɒˈskiː.təʊ/ (UK); /məsˈki.toʊ/ (US)[1]

Etymology

It is borrowed from Spanish mosquito (“little fly, gnat”),[2][3][4][5][6] a diminutive of mosca “fly”,[2][3][4][5][6] from Latin musca (“fly”).[2][3][4][5][6] The AHD also gives Portuguese as a source.[2] It is related to musket and midge.[2][4][5]

Earliest recorded meaning

A gnat of which the female sucks blood (about 1583).[7][3][2][5]

Semantic evolution

The meaning has stayed the same since the word was borrowed.[7][2] Compounds followed, such as mosquito-hawk, a dragonfly that preys on mosquitoes (1737), and mosquito net (1745).[4] From the insect's small size the name was given to light, fast boats and aircraft, as in mosquito craft (1804)[7] and the British Mosquito fighter-bomber of the Second World War.[6][1]

Timeline

  • about 1583 – the insect.[7][3][2][5]

  • 1745 – mosquito net.[4]

Usage notes

The AHD notes that mosquito and musket both go back to Latin musca “fly”: Italian moschetta, literally “little fly”, meant a crossbow bolt, because bolt and insect both fly, buzz and sting.[2]
