Etymology

Origin of ancillary

First recorded in 1660–70; from Latin ancillāris “having the status of a handmaid or female servant” + -ary adjective suffix; see origin at ancilla, -ary

---

Explanation

If you use the adjective ancillary to describe your position you are subordinate or supporting something or someone else. The adjective ancillary originally meant "relating to maidservants" from the Latin, but the element of a female servant has fallen away and now the word merely refers to a position as helpful or subordinate. An example of how something in medicine can be ancillary is after you have surgery you may also take a drug to aid healing — the drug would be considered ancillary to the surgery. One could also argue that in the United States the vice-president takes an ancillary role to the president.
