Morphology

auxiliary = auxili + ary

The stem 'auxili-' is a Latin combining form and not a standalone English base, so learners cannot reliably derive the meaning from its parts.

Etymology

The word auxiliary comes from the Latin word auxilium, which means 'help' or 'aid'. So an auxiliary power source or building is something that gives extra support or help.
