Questions & Answers about Проверь, пожалуйста, есть ли у нас молоко.
Проверь is the informal singular imperative of проверить.
So it means a direct instruction to one person: check.
- Проверь = tell one person you know well, a friend, a child, etc.
- Проверьте = formal singular or plural
Russian imperatives often omit the subject pronoun, so ты is understood here but not stated.
Because проверить is perfective, and here the speaker wants one complete result: do the check and find out.
- Проверь = check it once and get the answer
- Проверяй = keep checking / check regularly / be in the process of checking
In this sentence, the idea is not an ongoing activity. It is a single completed action, so проверь is the natural choice.
