auxiliary

Secondary support role

Auxiliary means providing support or assistance to something primary.

An auxiliary verb helps form tenses, moods, or voices of other verbs—words like *have*, *be*, *will*, *can*.

Auxiliary power backs up the main supply.

An auxiliary is a person or thing in a supporting role: hospital auxiliaries, auxiliary troops.

The word often appears in technical contexts where backup systems matter.
