adjutant

Etymology

Most dictionaries take it as borrowed from Latin adiūtāns (“helping”),^{[2][3][4][5][6][7][8]} the present participle of adiūtō (“to help, assist; to help zealously”),^[2][4][5][9] a frequentative of adiuvō (“to help, assist”),^{[2][5][9][10]} which is formed from ad- (“to”) and iuvō (“to help, give strength”).^[2][10][11] Etymonline suggests that the Latin verb may share its root with iuvenis (“young man”).^[2] The OED, revising its entry in 2011, takes the English word as probably partly borrowed from Spanish ayudante (“assistant, aide”), from ayudar (“to aid”), and partly borrowed from Portuguese ajudante (“assistant”), with its spelling remodelled after the Latin participle; its first quotation comes from a passage about the Spanish and Portuguese navies.^[12] Weekley had already thought it not taken straight from Latin but a remodelled form of the Spanish word, and noted that German Adjutant was a Spanish loan of the Thirty Years' War.^[13] adjudant also comes from the Spanish word.^[2][12] The Latin verb is the source of aid as well.^[9][4][3]

Earliest recorded meaning

An army officer who assists superior officers: 1600, in Philemon Holland's translation of Livy, according to Barnhart, and about 1600 in Etymonline.^[3][2] The revised OED has the general sense "assistant, helper" first, from 1622, and the military sense from 1641;^[12] Merriam-Webster gives 1539 as the first known use of the military sense.^[7]

Semantic evolution

Ayto notes that the word first meant simply an assistant, and that the military sense has now almost ousted that meaning;^[9][14] the OED and the Shorter Oxford call the general sense rare.^[15][8] The adjutant came to be the staff officer who handles a commanding officer's correspondence, records and administrative business.^[7][16][12] From 1798 the English in Bengal gave the name to a large stork, the adjutant bird or adjutant stork, for its stiff military gait;^{[12][2][13][6]} French adopted that sense from English in 1826.^[12] An adjective meaning "helping, auxiliary" was used from 1645 to 1880.^[12][7]
