"Do you eat bread?"

Translation: Ви їсте хліб?

[Vladimir.ch]

Why did you use only formal 'Ви'.I think it is equally correct to use informal form 'Ти'

[Vinnfred]

If it's not accepted, please report

[Kathy749975]

how do i know when to use Їм or їсте

[MomenMahmo5]

Same here

[KeithBarro5]

I think їм is when referring to yourself and їсте is for you/they/we?

[bar_an]

can you say "їсте хліб?" (without 'Ви')?

[Vinnfred]

I would say it's not very common for Ukrainian to omit pronouns

[vitas528]

yes, it is more informal

[Dianoya]

Why not? You can say it but I don't know it will be accepted or not.

"Ты їсиш..." и "Ви їсте..." оба варианта верны. Исправьте

[Dianoya]

Добавляйте правильные варианты через "флажок".

Whats the difference between ти and ви?

[JackyDW]

"Ти" is singular and informal, while "ви" is plural and formal.

I'm a beginner, how am I supposed to know all these words? I don't know what they mean, or how to even pronounce them.

[KirillG3]

Please use Duolingo on there website. For each lection there is a help/introduction where you can learn about the words. Other words you just learn during the lection. For most words you have a question where it's pronounced.
You shouldn't use Duolingo as the only source for learning a language, anyway.

Why doesnt it accept it in singular form?

[Gregory693653]

Ти їж хліб was rejected ...?

[Dianoya]

Yes. It's not that. You say something like: "Hey you, eat the bread!"
