aide

Etymology

It is probably partly borrowed from French aide (“assistant, helper”) and partly a shortening of aide-de-camp;^[2][3] Merriam-Webster, Barnhart, Etymonline and the Shorter Oxford call it simply short for aide-de-camp.^[4][5][6][7] The full term is aide-de-camp (“camp assistant”), recorded in Middle French from 1577, formed from “aide” with de (“of”) and camp (“camp”).^[2][6] The French noun comes from aider (“to aid”),^[3] from Latin adiūtō (“to help”), a frequentative of adiuvō (“to give help to”), from ad- (“to”) and iuvō (“to help”).^[6][3] It is the same word as aid, which English had borrowed from Old French centuries earlier.^[2][6]

Earliest recorded meaning

An assistant or helper, often in military contexts: 1762, in a letter of J. Jeffreys.^[2] Merriam-Webster, Barnhart and Etymonline date the word to 1777,^[4][5][6] and Dictionary.com to 1770–80, as an Americanism.^[8]

Semantic evolution

English had used aid for a person who helps since the 1560s,^[6][2] but the spelling aide came with the military officer: an officer assisting a senior officer, an aide-de-camp, from 1776 in American use.^[2][6] From 1837 an aide was also a personal assistant to a head of state or other leading politician.^[2] In the 20th century, chiefly in the United States, the word spread to assistants and ancillary workers, as in hospitals or in the homes of elderly or disabled people (1906).^[2] Barnhart notes that in the 1950s it began to be applied freely to any helper, as in a Red Cross aide or a White House aide.^[5]
