Polish: How do I know the stem of a verb?
If I understood it correct, there are two verb stems in Polish:
- infinitive stem
- present stem
In the most cases the infinitive stem is also the present stem:
- czytać - czyta- (stem)
The stem ist used to conjugate the verb, by adding the needed conjugation endings to the stem, i. e.
- czyta - czytasz
But some verbs have a different present stem.
- studijować - studiowa- (infinitive stem) - studiuj- (present stem)
Are these special verbs only these, where exist an "owa" in them? Or are there another ones?
And for the normal verbs: How do I know the stem? Only by remove the last letter, i. e. in czytać the ć? Or are there verbs, where this is different?
