Why isn't it "pijou" instead of "pijí"?
Both possibilities are correct.
Oh okay, thanks!
Doesn't pijí mean it's just female and pijou it's also male?
no, present forms of verbs do not distinguish genders
I guess it doesn't make as much sense, but one can think to himself "why do I drink bad beer", no ?
Difference is "i" and "í" in the word "piji"
"Proč pijí špatné pivo? " = Why do they drink bad beer?
"Proč piji špatné pivo? " = Why do I drink bad beer?
