So are there ти and ви forms of verbs for past tense?
Moreover, for ти there are separate verb forms for different genders:
Що вона робила? (feminine)
Що він робив? (masculine)
Що воно робило? (neuter)
Що вони робили (plural, all genders)
"ти" and "ви" in English mean the same - "you".
ти = informal, single;
ви = formal, plural
I already knew that. I just didn't realize that the past tense verbs change depending on whether formal or informal is used.
Aa... yes. And the same happens with future tense verbs.
