открывать vs открыть

otkryvat vs otkryt — open repeatedly/in progress vs open once

What it really means

Открыва́ть is imperfective: opening as an action in progress, a repeated action, or a general routine. Откры́ть is perfective: opening one thing once and reaching the resulting open state. The prefix от- is already part of both verbs; the contrast here is aspect, not a change in the basic meaning.

Use открывать for habits or a scene where the movement is unfolding: "Он открывает дверь" (He is opening the door). Use открыть when the request or result is bounded: "Открой окно" (Open the window).

Examples in natural speech

Она открывает дверь ключом.
She is opening the door with a key.
Магазин открывает двери в девять.
The shop opens its doors at nine.
Откройте книгу на странице десять.
Open the book to page ten.
Я открыл окно из-за жары.
I opened the window because it was hot.
Кто открыл эту коробку?
Who opened this box?

Common mistakes

Do not assume the perfective is required because opening happens only once. "Я открываю дверь" is natural if you are describing the action as it happens. Use открыть when you view the opening as one completed event or give a one-time command.

Memory tip

Открывать shows the opening motion; открыть shows the open result.

Frequently asked questions

What is the difference between открывать and открыть?

Открывать is imperfective for opening as a process, repeated action, or routine. Открыть is perfective for one bounded opening with the result in focus.

How do you say open the window in Russian?

Use the perfective command "Открой окно" when asking someone to open it once. "Открывай окно" can sound like an instruction to open it regularly or to start opening it.

Does открыть always mean the object stays open?

It presents the opening as completed, but context can determine what happens afterward. The perfective aspect guarantees a bounded event, not necessarily a permanent state.
