Aspect tells you whether an action is presented as a process or a completed whole. Aktionsart — спо́соб де́йствия, "mode of action" — tells you how the action unfolds: did it just begin, did it happen for a little while, did it go on all day, did it happen exactly once, was it overdone, did the doer keep at it until satisfied? Russian encodes these manners by bolting a prefix (or the suffix -ну-) onto a base verb, almost always producing a perfective. The result is one short word that carries a meaning English needs a whole phrase for: "to burst into song", "to sit for a bit", "to oversalt". This page maps the main modes so that you can both decode an unfamiliar prefixed verb and start to predict which prefix builds which nuance.
This builds directly on why a given perfective takes its prefix and on the catalogue of verb-prefix meanings. The key idea to hold throughout: these prefixed verbs are usually not the plain aspect partner of the base. запе́ть is not "the perfective of петь"; it is a new verb meaning "to start singing". Aktionsart prefixes create lexically new verbs that happen to be perfective.
Inceptive: за- and по- — "burst into / set off"
The inceptive marks the beginning of an action, often sudden. Two prefixes share the work. За- typically fits actions of sound, light, motion, and emotion that flare up: запе́ть "burst into song", закрича́ть "start shouting", засмея́ться "burst out laughing", заболе́ть "fall ill". По- marks the onset of directed motion: пойти́ "set off", побежа́ть "break into a run", повести́ "lead off".
Услы́шав но́вость, она́ запла́кала.
On hearing the news, she burst into tears. (за- inceptive: the onset of crying)
Он допи́л ко́фе и пошёл на рабо́ту.
He finished his coffee and set off to work. (по- inceptive of motion: пойти́ = 'set off')
Delimitative: по- — "do for a (short) while"
The same prefix по-, attached to a different kind of base, gives the delimitative: do the action for a bounded, usually modest, stretch of time. посиде́ть "sit for a bit", почита́ть "read for a while", погуля́ть "take a (short) walk", поработать "do a bit of work". The verb stays perfective but contains no result — it just frames a slice of activity, often with explicit немно́го or with a time phrase.
Дава́й посиди́м здесь мину́тку, я уста́л.
Let's sit here for a minute, I'm tired. (по- delimitative: a short bounded sit)
Ве́чером я хочу́ почита́ть и пора́ньше лечь спать.
In the evening I want to read a bit and go to bed early. (почита́ть = 'read for a while', not 'read through')
Perdurative: про- — "do throughout (a whole span)"
The perdurative про- fills an entire named period with the action — and often implies that the time was used up or wasted on it. проспа́ть весь день "sleep the whole day away", прорабо́тать три ча́са "work for three solid hours", проговори́ть всю ночь "talk all night long". A time phrase in the accusative (весь день, всю ночь, три ча́са) is almost obligatory; it is the span being filled.
Он проспа́л весь день и просну́лся то́лько ве́чером.
He slept the whole day away and only woke up in the evening. (про- perdurative: the full span filled by sleeping)
Мы проговори́ли на ку́хне до утра́.
We talked in the kitchen until morning. (про- perdurative: the night spent entirely talking)
Note that про- has a second, overlapping sense — "miss / overshoot through inattention" (проспа́ть рабо́ту "oversleep and miss work", прослу́шать ле́кцию "miss what was said in a lecture"). The delimitative and perdurative по-/про- pair are covered in more depth on delimitatives and perduratives.
Semelfactive: -ну- — "do it exactly once"
The semelfactive picks a single instantaneous instance out of an action that is naturally repeated. It is built not with a prefix but with the suffix -ну- on a base of repeated/iterative action: крича́ть "to (keep) shout(ing)" → кри́кнуть "to give one shout"; стуча́ть "to knock (repeatedly)" → сту́кнуть "to give one knock"; маха́ть "to wave" → махну́ть "to give one wave"; пры́гать "to jump (around)" → пры́гнуть "to make one jump". These are perfective and pluck out one quantum of the activity.
Кто́-то сту́кнул в дверь — оди́н раз, ти́хо.
Someone knocked at the door — once, quietly. (-ну- semelfactive: a single knock)
Она́ махну́ла руко́й на проща́ние.
She gave a wave goodbye. (махну́ть = one wave, vs маха́ть = waving)
Attenuative: под- and при- — "do a little / slightly"
The attenuative dials the action down: do it partially, gently, to a limited degree. под- and при- both serve here. поднажа́ть "push a bit harder / give it a bit more effort", подкорректи́ровать "tweak, adjust slightly", приоткры́ть "open slightly (a crack)", приле́чь "lie down briefly", присе́сть "sit down for a moment / squat slightly". The action is real but deliberately under-done.
Откро́й окно́ чуть-чу́ть — то́лько приоткро́й.
Open the window just a touch — only crack it open. (при- attenuative: open slightly)
Я приля́гу на полчаса́, разбуди́ меня́ в пять.
I'll lie down for half an hour, wake me at five. (приле́чь = lie down briefly)
Saturative: на-…-ся — "do until satisfied / to one's fill"
The saturative wraps the base in both the prefix на- and the reflexive particle -ся, and means "do the action until you have had your fill of it" — often with a connotation of satiety or even excess. нае́сться "eat one's fill", напи́ться "drink one's fill / get drunk", наговори́ться "talk to one's heart's content", наспа́ться "get all the sleep one wants", насмотре́ться "see enough / one's fill of". The object, if any, goes into the genitive (нае́сться су́па).
Наконе́ц-то я вы́спался и нае́лся как сле́дует.
At last I got enough sleep and ate my fill properly. (на-…-ся saturative: вы́спаться 'sleep enough', нае́сться 'eat one's fill')
Они́ так и не наговори́лись за весь ве́чер.
They still hadn't talked themselves out by the end of the evening. (наговори́ться = talk to one's full satisfaction)
Excessive: пере- — "overdo it"
The excessive пере- says the action went too far, past the right measure: пересоли́ть "to oversalt", перевари́ть "to overcook", переплати́ть "to overpay", переборщи́ть "to overdo it / go too far" (idiomatic), перегре́ть "to overheat". It contrasts neatly with недо- "underdo" (недосоли́ть "to undersalt").
Извини́, я немно́го пересоли́л суп.
Sorry, I oversalted the soup a bit. (пере- excessive: too much salt)
По-мо́ему, с украше́ниями ты переборщи́ла.
I think you went overboard with the decorations. (переборщи́ть = to overdo it)
Distributive: пере- and по- — "do to all of them, one by one"
A separate use of пере- (and of по-) is distributive: perform the action across a whole set, item by item, until all are covered. перебить всю посу́ду "smash all the crockery (every piece)", переписа́ть все докуме́нты "rewrite/copy out all the documents one after another", повыключа́ть свет во всех ко́мнатах "switch off the lights in all the rooms". The flavour is exhaustive coverage of multiple objects.
Во вре́мя землетрясе́ния перебило́ всю посу́ду в шкафу́.
During the earthquake all the crockery in the cupboard got smashed. (пере- distributive: every piece, one after another)
The distinguishing insight
The point that reorganises this whole topic: aspect is a two-way grammatical choice you must make for every verb; aktionsart is an open lexical layer that builds new verbs on top of it. Where aspect gives you the partner чита́ть / прочита́ть, aktionsart hands you a small fan of additional verbs around the same root — почита́ть (a while), зачита́ться (get absorbed in reading), перечита́ть (re-read / read too much), начита́ться (read one's fill) — each one a distinct lexical item with its own meaning, almost all of them perfective, none of them the simple aspect partner of the base. So when you meet an unfamiliar prefixed verb, don't ask "is this the perfective of X?" — ask "which mode of action has this prefix layered onto X?" Decode the prefix (за- onset, по- a-bit, про- throughout, -ну- once, под-/при- slightly, на-…-ся to satiety, пере- to excess) and the meaning falls out.
Common Mistakes
❌ Я хочу́ прочита́ть пе́ред сном.
Wrong if you mean 'read for a while' — прочита́ть means 'read through to the end'. For a bounded read use the delimitative почита́ть.
✅ Я хочу́ почита́ть пе́ред сном.
I want to read for a bit before bed. (по- delimitative)
❌ Он закрича́л три часа́.
Wrong — за- marks only the ONSET of shouting, so it can't take a duration. For 'shouted for three hours' use the perdurative прокрича́л три часа́ (or the imperfective крича́л).
✅ Он закрича́л от бо́ли.
He cried out in pain. (за- inceptive: the burst of shouting, no duration)
❌ Она́ кри́кнула не́сколько раз.
Mismatched — кри́кнуть is semelfactive ('give one shout'), so it clashes with 'several times'. For repeated shouting use крича́ла or покри́кивала.
✅ Она́ кри́кнула оди́н раз и замолча́ла.
She gave one shout and fell silent. (-ну- semelfactive: exactly once)
❌ Я о́чень нае́л за у́жином.
Wrong — the saturative needs -ся and takes a genitive object: я нае́лся (ate my fill). Without -ся, нае́сть means something else entirely.
✅ Я нае́лся за у́жином, бо́льше не могу́.
I ate my fill at dinner, I can't eat any more. (на-…-ся saturative)
Key Takeaways
- Aktionsart (спо́соб де́йствия) is a lexical layer on top of aspect: prefixes/the suffix -ну- add a manner and build new (usually perfective) verbs — not the plain aspect partner.
- Inceptive за-/по- = onset (запе́ть, пойти́); delimitative по- = do a while (посиде́ть, почита́ть); perdurative про- = fill a whole span (проспа́ть весь день).
- Semelfactive -ну- = do exactly once (кри́кнуть, махну́ть); attenuative под-/при- = do slightly/briefly (приоткры́ть, приле́чь).
- Saturative на-…-ся = do until satisfied, object in genitive (нае́сться, наговори́ться); excessive пере- = overdo (пересоли́ть, переборщи́ть); distributive пере-/по- = cover all objects one by one (перебить всю посу́ду).
- To read an unfamiliar prefixed verb, decode the prefix as a mode of action rather than assuming it is just "the perfective."

- Why This Prefix? Choosing the Perfective PartnerB2 — Which prefix perfectivizes a given imperfective is a lexical property you must learn WITH the verb, like gender (писа́ть→на-, чита́ть→про-, де́лать→с-). But many prefixes do more than perfectivize — they add a 'way of action' (спо́соб де́йствия): ЗА- begins, ПО- does a bit, ПРО- does throughout (or misses), ДО- finishes, ПЕРЕ- redoes, НА-...-СЯ does to satiety, РАЗ-...-СЯ gets going, ВЗ- does suddenly. Picking the wrong prefix often makes a DIFFERENT verb (переписа́ть 'rewrite' ≠ написа́ть 'write').
- Verb Prefixes and Their MeaningsB1 — A catalogue of the common Russian verbal prefixes and what they mean — spatial ones (в- in, вы- out, под- up to, от- away, пере- across/re-, про- through, за- behind/begin, при- toward, у- away, до- up to, раз- apart, с- together/off) and Aktionsart ones that tweak how an action unfolds (за- start, по- a bit/awhile, пере- redo/overdo, недо- not enough, до- finish). One root (писа́ть) runs through them all, and a Russian prefix works much like an English phrasal-verb particle (write → write down, write out, rewrite).
- Forming Aspect Pairs: PrefixationA2 — The commonest way the perfective is built: adding a prefix to an imperfective base. With a 'pure' perfectivizing prefix (про-, на-, с-, по-…) the meaning stays the same and only completion is added — but the prefix is lexically fixed and must be memorized per verb. Most other prefixes change the meaning and build a brand-new verb.
- Delimitative and Perdurative Verbs (по-, про-)C1 — Two aktionsart classes that bound an activity in time. The DELIMITATIVE prefix по- adds a short, casual dose ('do for a while / a bit'): посиде́ть, почита́ть, погуля́ть, поговори́ть. The PERDURATIVE prefix про- emphasizes the full extent of a long stretch ('do throughout the whole period, often with effort'): проговори́ть всю ночь, проспа́ть до полу́дня, прорабо́тать де́сять лет. Both are perfective, both take an accusative duration phrase, and they frame the same activity from opposite ends — a bit vs all the way through.
