After seeing drinky in a back page Times Book Review piece by Colson Whitehead (I still think of parts of The Illusionist, Colson Whitehead), and then thinking about diminutives, I decided it was time to get some of the what's what down.
Some of what's what is this, Latin suffixes-wise, via my Winston:
