In some language you can form several levels of diminutives from any noun. Even stuff that makes no sense, like "cute taxes", "cute death", "cute abstraction", "cute declension".
And you can form the opposite - take a noun and create less cute/uglier/larger version of it.
And these additional forms still obey the other rules, including declension. So there's a combinatorial explosion of versions of each word.
A cute abstraction would definitely be my thing. As we would say in Italian, an astrazioncella, or astrazionuccia, or astrazioncelluccia, or astrazioncinuccia, or astrazioncinelluccia. :)
They don't. Your teacher was a pervert. :)
Woda, wódka, wódeczka, wódzia, wódziunia.
and then if you don't like drinking you can go the other way:
wódka, wóda, wódzicha.
