As far as I can tell, longer diminutives (hooray, now I know the correct
English word!) such as "onok", "chok", "chek" and so on, do not affect meaning
in Russian that much (or at all). To my experience, removing some of the
longer and safer of these suffixes along with their respective cases
(eg: "onok", "onku", "onkom") just allows to account for the case, so,
say, "zaichonok" and "zaichonku" would reduce to the same stem without
affecting much else. So it's pretty safe to me.
