Telling a story is where aspect stops being a textbook abstraction and becomes the very engine of the narrative. English narrates with two tools — the simple past ("he cooked, she left") to advance the plot, and the past continuous ("she was cooking, the rain was falling") to set the scene. Russian does the same job with aspect: the perfective advances, the imperfective sets the scene. The errors below are all the same mistake in different clothes — choosing a Russian verb to match an English tense instead of asking what the verb is doing in the story. Get the division of labour right and your narration suddenly sounds native. For the underlying theory see aspect in the past.
Background is imperfective; foreground is perfective
The single most useful pattern in narration: when one action is in progress and a second, completed action breaks into it, the background goes imperfective and the interrupting event goes perfective. English signals this with "was -ing" + "when … did". Russian signals it with imperfective + perfective. The error is to make the background perfective, which turns a scene-setting "was cooking" into a completed "finished cooking" and rewrites the meaning.
❌ Когда́ я пришёл, она́ пригото́вила у́жин.
Wrong if you mean 'was cooking' — the perfective пригото́вила means she had finished; it reads 'when I came in, she made dinner (at that moment)'.
✅ Когда́ я пришёл, она́ гото́вила у́жин.
When I came in, she was cooking dinner. — background process (imperfective) interrupted by my arrival (perfective).
✅ Когда́ я пришёл, она́ уже́ пригото́вила у́жин.
When I came in, she had already cooked dinner. — here the perfective is right: the result was in place before I arrived (note уже́).
The two correct versions are both good Russian — they just tell different stories. The imperfective one puts us inside the cooking; the perfective one reports a finished meal waiting on the table. Choosing between them is choosing what the listener sees.
A one-time sequence is a chain of perfectives
When you list the events of one particular occasion — "this morning I got up, got dressed, and left" — each event is a single completed step, and the whole chain is perfective. English uses the plain past for both a one-off and a routine ("I got up, dressed, left"), so learners reach for the imperfective and accidentally describe a habit instead of today's events.
❌ Сего́дня у́тром я встава́л, одева́лся и уходи́л.
Wrong for one morning — these imperfectives describe a recurring routine ('I used to get up, dress, leave'), not today's single sequence.
✅ Сего́дня у́тром я встал, оде́лся и ушёл.
This morning I got up, got dressed, and left. — a chain of single completed events → perfectives.
✅ Ра́ньше я ка́ждое у́тро встава́л, одева́лся и уходи́л на рабо́ту.
I used to get up, dress, and leave for work every morning. — a recurring routine → imperfectives.
The dividing line is once vs. repeatedly. A single morning's events advance like beads on a string (perfective); a typical morning describes the open, repeated routine (imperfective). See the aspect choosing guide for the full decision procedure.
Don't import the English "historic present"
English storytelling, especially casual or dramatic ("So I walk in, and she says…"), often slides into the present tense to make past events feel vivid. This historic present exists in Russian too, but it is a deliberate stylistic device, not the default — and beginners produce it by accident, simply because they reach for the present-tense forms they know best while narrating something that happened yesterday. The result is a jarring tense clash with the past-tense verbs around it.
❌ Вчера́ иду́ я по у́лице и ви́жу ава́рию, и пото́м прие́хала поли́ция.
Clashing — an accidental present (иду́, ви́жу) jammed against a past (прие́хала); keep one frame.
✅ Вчера́ я шёл по у́лице и уви́дел ава́рию, а пото́м прие́хала поли́ция.
Yesterday I was walking down the street and saw an accident, and then the police arrived. — consistent past: imperfective background (шёл) + perfective events.
If you want the vivid effect, commit to it for the whole stretch (Иду́ я вчера́, ви́жу ава́рию, тут подъезжа́ет поли́ция…) — but don't drift into it by accident mid-sentence. As a learner, narrate the past in the past until the present-for-past device is a conscious choice.
After когда́/как то́лько, a future event takes the future — not the present
English narration of a planned future slips into the present after "when / as soon as": "When I get there, I'll call." Russian keeps both clauses in the future. Writing a present (приезжа́ю) where you mean a future arrival is one of the most systematic English-transfer errors, and it doubles as an aspect error, since the future event is usually a single completed one (perfective прие́ду).
❌ Когда́ приезжа́ю в Москву́, я тебе́ позвоню́.
Wrong for a future plan — the present приезжа́ю reads as a habit ('whenever I arrive…'); a single future arrival is future perfective.
✅ Когда́ прие́ду в Москву́, я тебе́ позвоню́.
When I get to Moscow, I'll call you. — both clauses future; the single arrival is perfective.
✅ Когда́ приезжа́ю в Москву́, всегда́ тебе́ звоню́.
Whenever I come to Moscow, I always call you. — here the present is correct: a genuine habit.
So приезжа́ю is not wrong in itself — it is wrong for a single future event. For a recurring habit ("whenever I come"), the present is exactly right. The full rule is on future in subordinate clauses.
The distinguishing insight: narrate by function, not by English tense
English packs four jobs — plot advancement, scene-setting, vividness, and future-after-"when" — into the simple past, the continuous, and the present. Russian re-sorts all four into the aspect choice plus one tense rule (future stays future). So when you narrate, stop translating the English tense and instead label each verb's function: advance the plot → perfective; set the scene / describe an ongoing or repeated state → imperfective; a future event after когда́/е́сли → future (perfective if it's a single completed event). Almost every narration error above dissolves the moment you sort verbs by function instead of by their English tense form.
Common Mistakes
❌ Когда́ зазвони́л телефо́н, я посмотре́л фильм.
Wrong if you mean 'was watching' — the perfective посмотре́л means you watched it through; the background of an interruption is imperfective.
✅ Когда́ зазвони́л телефо́н, я смотре́л фильм.
When the phone rang, I was watching a film.
❌ Вчера́ ве́чером я гото́вил у́жин, помы́л посу́ду и лёг спать.
Mixed up — for a one-off chain of completed events all three should be perfective.
✅ Вчера́ ве́чером я пригото́вил у́жин, помы́л посу́ду и лёг спать.
Last night I made dinner, washed the dishes, and went to bed.
❌ Я открыва́ю дверь, а там стоя́л незнако́мец.
Clashing — an accidental present (открыва́ю) against a past (стоя́л); keep the past frame.
✅ Я откры́л дверь, а там стоя́л незнако́мец.
I opened the door, and there stood a stranger.
❌ Как то́лько зака́нчиваю рабо́ту, я тебе́ напишу́.
Wrong for a single future — a future completion after как то́лько is future perfective.
✅ Как то́лько зако́нчу рабо́ту, я тебе́ напишу́.
As soon as I finish work, I'll text you.
❌ Ка́ждый ве́чер он сде́лал уро́ки и смотре́л телеви́зор.
Wrong — 'every evening' is a habit; both verbs should be imperfective.
✅ Ка́ждый ве́чер он де́лал уро́ки и смотре́л телеви́зор.
Every evening he did his homework and watched TV.
❌ Я чита́л э́ту кни́гу за два дня и о́чень понра́вилась.
Wrong frame — 'in two days' marks a completed whole, so the reading is perfective; and понра́вилась needs its subject.
✅ Я прочита́л э́ту кни́гу за два дня, и она́ мне о́чень понра́вилась.
I read this book in two days, and I really liked it.
Key Takeaways
- Aspect is the engine of narration: imperfective sets the scene (background, ongoing, habitual), perfective advances the plot (single completed events).
- An interruption pairs them: imperfective background + perfective event (Когда́ я пришёл, она́ гото́вила).
- A one-off sequence is a chain of perfectives (встал, оде́лся, ушёл); imperfectives there describe a recurring routine.
- Don't drift into the English historic present by accident; narrate the past in the past unless the vivid present is a deliberate, sustained choice.
- After когда́ / как то́лько / е́сли, a single future event stays future (and usually perfective): Когда́ прие́ду…, not Когда́ приезжа́ю…
- The fix for all of these: classify each verb by its function in the story, not by the English tense you'd use.

- Choosing Aspect in the Past TenseB1 — Both aspects have past forms, so every past-tense sentence forces a choice: imperfective for process, repetition, duration, background and general experience (я чита́л — was reading / read for a while), perfective for a single completed action with a result and for sequences of events (я прочита́л — read it through); this is the single most consequential aspect decision in the language.
- Future Tense in Subordinate ClausesB1 — English says 'when I arrive [present], I'll call'. Russian puts BOTH clauses in the future: Когда́ я прие́ду, я тебе́ позвоню́. After когда́, е́сли, как то́лько, пока́ referring to a future event, the subordinate verb must be future — writing a present there (*Когда́ я приезжа́ю…*) is one of the most systematic English-transfer errors.
- Decision Guide: Imperfective or Perfective?B1 — A practical, question-ordered procedure you run for every verb. Most aspect agonizing disappears once you notice that some choices are forced (present tense and phase verbs are always imperfective) and the rest reduce to one real question: process or completed result? This page gives you a checklist and walks sentences through it.
- Aspect Errors English Speakers MakeB1 — The aspect mistakes that mark an English speaker instantly: using a perfective for a habit (Ка́ждый день я прочита́ю), an imperfective for a finished result (Я уже́ де́лал, meaning 'done'), a perfective infinitive after a phase verb (на́чал прочита́ть), imperfectives for a one-off morning sequence (встава́л, одева́лся, уходи́л), and the prohibition/warning flip in negative commands (Не закро́й vs Не упади́). The cure is to decide aspect FIRST, before you even pick the word.
