Suffixes have to do with the evolution of language.

For example, words ending in “ion” refer to the “act or state of” (examples:) confusion, correction, protection

“en” refers to “made of, to make” as in “woolen, wooden, darken”

Offhand, I don’t know the morphological decomposition of the morpheme (in) vs (on) but I remember studying suffixes like this in Linguistics in college. You should go to your library and look over books found near any of these selections–that would put you in the right location to find the best references for this kind of practical linguistic deconstruction.

Those words you provided…???

Venison?

It’s not like the prefixes Mc and Mac or Mg and Mag, which indicate whether the names stems from the father or the mother. Nothing like that, I say it’s just random, no rule.

Whoever heard of a baten or a baboen.

I’ve eaten a lot of venison but never any venisen, vinison, or venicine.

Also had a vaccination but never a vaccinatien.

Once had a vixen as a pet but never a vixon.

Oh well, you get the point.
