Forms
ejército m (plural ejércitos)[1] Old Spanish wrote exército or exérçito;[2][1] Wiktionary gives exército as an alternative form.[2][1]
Etymology
It is inherited from Old Spanish exército, borrowed from Latin exercitus (“physical exercise; army”), a learned word.[1][3][4][5] The DCECH explains the Latin noun as properly “a body of men trained for war”.[4] Like ejemplo, the borrowing was read with the Old Spanish value of ⟨x⟩, /ʃ/, rather than /ks/, and so took the modern /x/ and the spelling ⟨j⟩.[1]
The Latin noun is an action noun from exerceō (“to keep busy, exercise”) with the suffix -tus.[6][1] The verb is a compound of arceō (“to contain, keep out”), as Corominas and de Vaan both say.[4][7] De Vaan reconstructs a Proto-Indo-European causative verb meaning “to hold”, and compares Ancient Greek ἀρκέω (arkéō, “to ward off, defend; to suffice”).[7] Wikcionario gives the root as Proto-Indo-European *h₂erk-.[8]
The same Latin word was borrowed as Catalan exèrcit, Italian esercito and Asturian exércitu.[9][10][11] Spanish passed it on to Guarani ehérsito and Tagalog ehersito.[1]
Earliest recorded meaning
The CDH's earliest hit, in the Avisación de la dignidad real (after 1325), survives only in a copy of 1449.[2] The first text without a later copy is Juan Fernández de Heredia's Gran crónica de España (1376–1391): sallio de Valladolid con todo su exercito et fue a Palencia “he left Valladolid with all his army and went to Palencia”.[2] Corominas dates the word to about 1440, in Juan de Mena and the Marquis of Santillana.[4][5]
Semantic evolution
The word entered Castilian as a learned term, used by Mena, Santillana and Alfonso de Palencia in the 15th century and by Pero Mejía in 1545.[4] It replaced the medieval word for an army, hueste, only slowly.[4] Nebrija and Pedro de Alcalá still give only hueste, and Nebrija glosses Latin exercitus as la ueste de gentes.[4][12] By the Quijote it already sounds like an everyday word.[4] In the Americas it is recorded from 1532, in Mexico.[13]
The Academy's dictionary of 1817 describes an army as a great number of soldiers of infantry and cavalry under a general, and records the thieves' slang sense “prison”.[14][15] Domínguez (1846) adds “swarm, crowd, multitude”, a sense the Academy then left out.[16] The 1899 edition adds “the land forces of a nation”.[17] In old Aragon ejército was also the name of a tax.[18]
