Questions & Answers about Поставь кружку на полку, пожалуйста.
Why is поставь used here—what tense/mood is it?
Поставь is the imperative mood (a command/request) of the verb поставить (perfective aspect). It tells someone to do a single, completed action: “put (it) (down/onto something).”
Why is it поставь and not ставь?
This is about aspect:
- поставь (from поставить, perfective) = “put it (once), place it (and finish).”
- ставь (from ставить, imperfective) = often “be putting/placing,” “place (habitually),” or “start placing” depending on context.
In everyday requests like this, Russian commonly uses the perfective imperative to mean “do it (one time).”
Who is being addressed—ты or вы?
Поставь is the informal singular imperative (addressing ты).
For polite/formal or plural, you’d use:
- Поставьте кружку на полку, пожалуйста.
