I'm not doing this for me- I want to make it available for downloading on SkyrimNexus. Ideally, someone here would point me to a collection of non-human sayings or words that I can then pick through, decipher and record.
What I meant was "what race do you need words for?" We have pretty good vocabularies for Dunmer, Ayleid, and general Ehlnofex, but they're quite different. Your best bet in general would be TIL's dictionary which Moophl linked.
Only Dwemeri is independent of Aldmeri, as far as I know.
Ayleid is pretty different, too.
