I am trying to phrase something like:
We argue that introducing these concepts is likely to achieve ancillary goals.
Should I use auxiliary or ancillary here? Is there a difference in meaning?
Ancillary carries with it the idea of support for main goals:
Auxiliary has connotations of supplementary or "extra" help:
Use whichever works best for your meaning.
The meaning of ancillary is also "additional, subsidiary".
If you wrote "ancillary goals" to mean "additional goals", then "ancillary goals" seems fine, to me.
