From Latin auxili- (help).

Word Ancestry
from Latin auxiliārius (“assistant, ally”), equiv. to auxiliāris (“helping, aiding”)
Picture a Roman commander keeping a second force just behind the battle line: not the main legion, but troops ready to rush in when things became difficult. Latin called such help auxilium, and its adjective auxiliārius meant “helping” or “belonging to an ally.” English adopted auxiliary around 1600, giving us a word for backup troops, extra equipment, and even the small grammatical verbs that support a main verb, as in “may,” “have,” or “will.” The family is tied to Latin augēre, “to increase,” so assistance was imagined as something that adds strength rather than merely standing nearby. In modern slang, “auxiliary” can even be used jokingly for something excessively or awkwardly extra—but its oldest image remains wonderfully practical: the thing waiting just offstage until the main act needs reinforcement.
