Questions & Answers about Ви заповните документ.

What does Ви mean here? Is it singular or plural?

Ви can mean either:

• you when speaking to more than one person
• you when speaking to one person politely/formally

So this sentence could address:

• a group: You all will fill out the document
• one person formally: You will fill out the document

The informal singular pronoun would be ти.

Why is Ви capitalized?

In this sentence, Ви is capitalized simply because it is the first word of the sentence.

More generally, in Ukrainian writing, Ви with a capital letter can also be used as a polite form when addressing one person, especially in letters, emails, forms, and official communication. But in this sentence alone, the capital letter does not prove that it is formal singular, because sentence-initial words are capitalized anyway.

What form is заповните?

заповните is the 2nd person plural form of the verb заповнити.

With Ви, that means it matches either:

• you all will fill out
• you will fill out (formal singular)

Grammatically, it is a future tense form.
