Pronunciation

  • /eskwaˈdɾon/, [es.kwaˈð̞ɾõn][1]

Forms

escuadrón m (plural escuadrones)[1] It was often spelt esquadrón in the 15th and 16th centuries.[2][3]

Etymology

Corominas thinks it is probably borrowed from Italian squadrone, which is found in Machiavelli and which also gave French escadron at the end of the 15th century.[4][5][1] The DLE and Wiktionary instead treat it as formed in Spanish, from Spanish escuadra (“squad”) + -ón, with the augmentative suffix.[6][1]

The Italian word is an augmentative of squadra (“squad, team”), from the verb squadrare (“to square”).[7] Nocentini traces the verb to Vulgar Latin *exquadrāre, from Latin quadrō (“to make square”) with the prefix ex-.[8] The Latin verb is from quadrus (“square”).[1]

Earliest recorded meaning

The earliest CDH hit is the Crónica del halconero de Juan II (before 1454), known only from a 16th-century copy: salieron seys esquadrones grandes “six large squadrons came out”.[2] Corominas dates it to the end of the 15th century, in the chronicle of Enrique IV;[9] Alonso Maldonado's chronicle of about 1492 speaks of a commander and todo su escuadrón “all his troop”.[4][2]

Semantic evolution

At first it was a body of soldiers drawn up in ranks for battle.[2][9] In the Americas it is recorded from 1533, often of bodies of Indian warriors.[3] Terreros defined it as a body of cavalry drawn up for battle, and recorded escuadrón volante for a group of cardinals in a conclave who stand apart from the courts' interests.[10] The Academy's 1899 dictionary made it a division of a cavalry regiment, and gave the older senses “troop formed in ranks” and “part of an army of infantry and cavalry”.[9] It has also become a unit of the air force, equivalent to a battalion.[6]
