Sorry, no etymologies found.
There's the old stand-bys: inversion, retrograde, combinatoriality (be the context tonal or atonal).
I don't think that freshmen, or even undergrads, really, should be expected to be grad-level fluent in Schenkerian analysis, or set theory, or the more esoteric corners of combinatoriality — I'd be happy with just a solid grounding in history, form, and Roman numeral-style analysis — but they should definitely be aware of their existence and their applicability.
