"What do you like to do?"

Translation: Що ви любите робити?

[oathbound]

Is the pronoun necessary? In many conjugated languages the pronoun is unnecessary unless the context is ambigious. How does this work in Ukrainian?

[deactivated user]

In short, the pronoun is neccessary.

The pronoun can only be dropped when there is some context. Usually when the previous sentence had the same subject. However, when you just have one sentence without prior context, dropping pronoun sounds extremely weird.

Ah, ok, thanks for explaining.

why is Шо ти любиш робити wrong?

[deniko]

Шо->Що

Що ти любиш робити?

Цей варіант приймається.

Exactly.. it is really strange

[NathalieMu602081]

It could be singular form

[Rick404649]

I assume that Duolingo is (for now) a little 'stubborn' (I don't know which right word to use actually, I'm not an Englishman).
They only accept one way, one answer.

Because 'you' definitely means both 'ти' and 'ви' (ви singular in this context).

[Arne2485]

Please have this changed, so that both ти любиш and ви юбите will be accepted as correct.

Why can't I do як instead of що?

[J7jx10]

"Як" means HOW whereas the question is WHAT
