The Imperfective: Process, Repetition, General Fact | Russian Grammar

The imperfective (несоверше́нный вид — "incomplete aspect") is the aspect you reach for when you are not presenting an action as a single, finished, result-bearing whole. That covers far more ground than English speakers expect, because the imperfective is the home of the process, the habit, the general fact, the failed attempt, and the action that was later undone. If the overview gave you the headline — process vs. completed whole — this page catalogues exactly when "process" is the right reading. (The perfective's territory is the next page.)

A useful anchor before the list: the present tense is always imperfective, because describing what is going on right now is, by definition, viewing an action from the inside. Every present-tense verb you have ever met is imperfective.

Я живу́ в Москве́ и рабо́таю в ба́нке.

I live in Moscow and work at a bank. — present tense, so necessarily imperfective: ongoing states and habits.

1. Process — an action in progress

The most basic use: the action unfolding, "was doing / were doing," with attention on the activity itself rather than any endpoint.

— Что ты де́лал вчера́ ве́чером? — Чита́л.

'What were you doing yesterday evening?' 'Reading.' — де́лать / чита́ть (imperfective): the focus is how the time was spent.

Когда́ я вошёл, она́ говори́ла по телефо́ну.

When I came in, she was talking on the phone. — говори́ть (imperfective): an action in progress, the background to my arrival.

Note that the process reading carries no claim of completion. Я чита́л кни́гу says I was engaged in reading a book; whether I finished it is left entirely open (and if I did finish, you would switch to the perfective прочита́л).

2. Repetition and habit

For anything done repeatedly, regularly, or as a custom — every day, often, usually, on Mondays — the imperfective is obligatory. A completed whole cannot be repeated and stay a single whole, so repetition rules out the perfective.

Он ка́ждый день звони́л ма́ме.

He used to call his mother every day. — звони́ть (imperfective): habitual, repeated.

По суббо́там мы обы́чно ходи́ли в кино́.

On Saturdays we usually went to the movies. — repeated habit.

Ра́ньше я мно́го кури́л, а тепе́рь бро́сил.

I used to smoke a lot, but now I've quit. — кури́ть (imperfective) for the past habit; бро́сить (perfective) for the single, finished act of quitting.

💡

Time words are reliable signposts. ка́ждый день (every day), всегда́ (always), ча́сто (often), обы́чно (usually), иногда́ (sometimes), по понеде́льникам (on Mondays) all force the imperfective. See aspect with time words for the full list.

3. The general fact — naming the action, not its result

This use trips up English speakers the most. Sometimes you simply want to assert that an action took place at all — its name, the bare fact of the experience — with no interest in whether it was completed or what resulted. Russian uses the imperfective for this "general-factual" statement, and it very often corresponds to the English present perfect of experience.

Ты чита́л «Войну́ и мир»?

Have you (ever) read War and Peace? — чита́ть (imperfective): asking about the experience, the fact of having engaged with it — not whether you finished every page.

Ты ви́дел э́тот фильм?

Have you seen this film? — ви́деть (imperfective): the experience, the general fact.

Кто стро́ил э́тот дом?

Who built this house? — стро́ить (imperfective): identifying the agent, naming the past activity, with no focus on the finished result.

The contrast with the perfective is sharp and worth feeling. Ты прочита́л «Войну́ и мир»? (perfective) asks specifically did you finish it — did you get all the way through the book you started? Ты чита́л…? (imperfective) asks the broader have you ever read it / are you familiar with it. English hides this difference; Russian makes it a choice you cannot dodge.

4. Attempt without success — the conative imperfective

Because the imperfective makes no claim about a result, it is the natural aspect for an action you tried to do but did not bring off. The perfective partner, by contrast, would assert that the result was achieved.

Я реша́л э́ту зада́чу весь ве́чер, но так и не реши́л.

I worked on this problem all evening but never solved it. — реша́ть (imperfective) = the attempt/process; реши́ть (perfective) = the achieved solution, here negated.

Он до́лго угова́ривал меня́, но я не согласи́лся.

He spent a long time trying to talk me into it, but I didn't agree. — угова́ривать (imperfective): the effort, not a completed persuasion.

Я звони́л тебе́ весь день!

I was calling you all day! — звони́ть (imperfective): repeated attempts; it doesn't claim the call ever connected (compare perfective дозвони́лся = got through).

5. The annulled or two-way result

Here is the imperfective use with no clean English counterpart, and the one that most often surprises learners. The imperfective past can describe an action whose result has since been reversed — the thing was done, then undone, so the situation is now back as it was. The perfective, by contrast, presents a result that still stands.

Compare the classic minimal pair:

Imperfective — annulled result	Perfective — result stands now
Я открыва́л окно́. — I opened the window (and it's now closed again / I had it open for a while).	Я откры́л окно́. — I opened the window (and it's open now).
Ко мне приходи́л брат. — My brother came round (he came and went; he's not here now).	Ко мне пришёл брат. — My brother has come / arrived (and he's still here).

Кто открыва́л окно́? В ко́мнате хо́лодно.

Who's been opening the window? It's cold in here. — открыва́ть (imperfective): the window was opened and is now closed again; the speaker is asking who did it, not pointing at an open window.

Я брал твою́ кни́гу, но уже́ верну́л на по́лку.

I borrowed your book, but I've already put it back on the shelf. — брать (imperfective): the taking was reversed; the book is back where it was.

💡

The annulled-result imperfective is why a sentence that looks completed in English ("Someone opened the window") may need the imperfective in Russian — because the action was undone. Ask yourself: does the result still hold? If yes → perfective (откры́л). If the action was reversed or you're just identifying who did it → imperfective (открыва́л). This is treated in depth on result and annulment.

6. Simultaneous background actions

When two actions run in parallel — both unfolding at once, neither bounded against the other — both go imperfective.

Пока́ я гото́вил у́жин, жена́ накрыва́ла на стол.

While I was making dinner, my wife was setting the table. — гото́вить / накрыва́ть (both imperfective): two parallel processes.

Он сиде́л у окна́ и смотре́л на дождь.

He sat by the window watching the rain. — сиде́ть / смотре́ть (imperfective): a sustained, ongoing scene.

Contrast this with a sequence of completed steps ("he stood up, got dressed, and left"), which takes the perfective — covered on the perfective page.

Why English speakers undershoot the imperfective

English overwhelmingly maps "I did X" onto a finished event, so learners reach for the perfective by reflex. But several of the uses above describe completed-looking situations that Russian still treats imperfectively:

Experience questions ("Have you read…?", "Have you seen…?") → imperfective, because you are naming the activity, not certifying completion.
Identifying the agent ("Who built this?") → imperfective.
Annulled results ("Someone opened the window" — now closed) → imperfective.
Failed attempts ("I worked on it but didn't solve it") → imperfective.

The unifying logic: the imperfective views the action from the inside — as activity, repetition, or bare fact — and stays silent about any boundary or result. Whenever the boundary/result is not the point, the imperfective is correct, even when English would use a plain past or a present perfect.

Common Mistakes

❌ Ты прочита́л Толсто́го? (meaning 'are you familiar with Tolstoy')

Wrong for an experience question — прочита́л (perfective) asks 'did you finish reading him'. For the general experience, use the imperfective чита́л.

✅ Ты чита́л Толсто́го?

Have you (ever) read Tolstoy?

❌ Я сде́лал э́то упражне́ние ка́ждый день.

Wrong — 'every day' is repetition, which is incompatible with the perfective's single-whole reading. Use the imperfective де́лал.

✅ Я де́лал э́то упражне́ние ка́ждый день.

I did this exercise every day.

❌ Я реши́л зада́чу, но не реши́л её.

Self-contradictory — реши́л (perfective) already asserts the problem was solved, so you can't then deny it. For the attempt, use the imperfective: Я реша́л зада́чу, но не реши́л.

✅ Я реша́л зада́чу, но не реши́л.

I worked on the problem but didn't solve it.

❌ Сейча́с я напишу́ ка́ждое у́тро дневни́к.

Wrong twice — perfectives have no present, and a habit ('every morning') needs the imperfective present anyway. Use пишу́.

✅ Ка́ждое у́тро я пишу́ дневни́к.

Every morning I write in my diary.

Key Takeaways

The imperfective views an action from the inside and makes no claim about a result or boundary.
Six core uses: process (was doing), repetition/habit (every day), general fact / experience (have you ever…), failed attempt (tried but didn't), annulled result (did it, then undid it), and simultaneous background (while X, Y).
The present tense is always imperfective.
It frequently matches the English present perfect of experience (Ты ви́дел…? = Have you seen…?) and the annulled-result use has no clean English equivalent (Кто открыва́л окно́? = who opened it — and it's closed again).
When the result/boundary is not the point, choose the imperfective — even if English would use a plain past.
