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:
providing necessary support to the primary activities or operation of an organization, institution, industry, or system : the development of ancillary services to support its products.
Auxiliary has connotations of supplementary or "extra" help:
providing supplementary or additional help and support : an auxiliary nurse | auxiliary airport staff.
Use whichever works best for your meaning.
The meaning of ancillary is also "additional, subsidiary".
Paragraph 19 was merely ancillary to paragraph 16.
If you wrote "ancillary goals" to mean "additional goals", then "ancillary goals" seems fine, to me.
Thank you for your interest in this question.
