Etymology

It is borrowed from Italian squadrone (“body of soldiers in square formation”),[2][3][4] the augmentative of squadra (“square; battalion”).[5][6][3][7] The Italian word comes from the same source as square,[7][8] and is also the source of squad.[7][9] From Italian the word also passed into escuadrón, esquadrão and escadron,[4][10] and into Schwadron.[10]

Earliest recorded meaning

A body of soldiers drawn up in a square: 1562, in John Shute's translation of Cambini's account of the Turkish wars.[3][4][6]

Semantic evolution

As Ayto puts it, a squadron is etymologically a "square": the military sense comes from the formation in which the troops were drawn up.[7] The square formation itself went out of use by the mid 17th century;[4][8] already in 1579 the word meant a small body or detachment of soldiers in general.[4][3] In the 18th and 19th centuries it was especially a division of a cavalry regiment;[6][4] it was applied to a division of a fleet from 1588,[3][4] and to a unit of an air force from 1912 or 1913,[4][6][3] which Weekley counted among the naval terms taken over by the air service.[10] Since 1617 it has also meant any fairly large organized group of people,[4] and since 1670 a group of cardinals between the main factions of a conclave.[4] In colonial America it was for a time a ward or district of a town.[4]
