Plural of auxiliary; supplementary troops, workers, or components that provide support or aid to a main force or system.
From Latin 'auxilium' (aid, help) + '-aries' (plural). Originally military term for non-citizen troops supporting Roman legions, later generalized to any supporting group.
Roman 'auxiliaries' were non-citizen troops who fought on the empire's borders—not in the prestigious legions—yet archaeological evidence shows they were often more adaptable and effective, teaching us that 'secondary' doesn't mean 'less important.'
