Morphology

ancillary = ancill + ary

The adjective is a borrowing formed from a non‑productive Latin base ('ancill-') plus the suffix '-ary'; the base is not a recognizable English word, so learners cannot reliably derive the meaning from its parts.

Etymology

Ancillary comes from the Latin word ancilla, which means 'maid' or helper. So an ancillary thing or service is something that gives extra help or support to the main activity.
