Adjective

Auxiliary can be used in a wide range of capacities in English to describe a person or thing that assists another. A fire department may bring in auxiliary units, for example, to battle a tough blaze, or a sailboat may be equipped with auxiliary engines to supply propulsion when the wind disappears. In grammar, an auxiliary verb assists another (main) verb to express person, number, mood, or tense, as have in "They have been informed." The Latin source of auxiliary is auxilium, meaning "help."
