Ancillary vs. Corollary — What's the Difference?

Of secondary importance; subordinate

In mathematics and logic, a corollary ( KORR-ə-lerr-ee, UK: korr-OL-ər-ee) is a theorem of less importance which can be readily deduced from a previous, more notable statement. A corollary could for instance be a proposition which is incidentally proved while proving another proposition, while it could also be used more casually to refer to something which naturally or incidentally accompanies something else (e.g., violence as a corollary of revolutionary social changes).

Auxiliary or accessory

A proposition that follows with little or no proof required from one already proven.

Something that is subordinate or accessory to something else

A deduction or an inference.

(rare) Forming a proposition that follows from one already proved.

That which is given beyond what is actually due, as a garland of flowers in addition to wages; surplus; something added or superfluous.

A practical consequence that follows naturally;

(logic) an inference that follows directly from the proof of another proposition
