The imperfetto is one of the two essential past tenses in Italian, alongside the passato prossimo. Where the passato prossimo zooms in on completed past events, the imperfetto zooms out: it paints backgrounds, describes states, narrates habits, and stretches actions across time without specifying when they ended. If the passato prossimo is a snapshot, the imperfetto is the rolling video footage behind it.
For English speakers, the imperfetto is initially confusing because there is no single English equivalent. Depending on context, mangiavo translates as I was eating, I used to eat, I would eat (habitually), I ate (when describing a routine). English distributes these meanings across several different forms; Italian collapses them into one tense whose internal logic is "unbounded past."
Once you internalize that logic — that the imperfetto marks an action without telling you when it ended — your past-tense storytelling will start to sound natural. Until then, English speakers tend to overuse the passato prossimo, treating every past event as a discrete completed point even when the meaning is descriptive or habitual.
The endings
The imperfetto has a single set of endings shared across all three regular conjugation classes — with the only difference being the linking vowel (a, e, i) inherited from the infinitive. This is one of the most regular tense systems in the entire Italian verb paradigm: once you know one verb, you can conjugate all of them, including most of the otherwise irregular ones.
| Person | parlare (-are) | credere (-ere) | dormire (-ire) | capire (-ire -isco — same as dormire!) |
|---|---|---|---|---|
| io | parlavo | credevo | dormivo | capivo |
| tu | parlavi | credevi | dormivi | capivi |
| lui / lei / Lei | parlava | credeva | dormiva | capiva |
| noi | parlavamo | credevamo | dormivamo | capivamo |
| voi | parlavate | credevate | dormivate | capivate |
| loro | parlàvano | credévano | dormívano | capívano |
Two huge wins from this table:
The -isco subgroup of -ire vanishes in the imperfetto. Verbs like capire, finire, preferire, pulire behave exactly like dormire here — no -isc- anywhere. Capisco (presente) but capivo (imperfetto). Same for finire (finivo, not finiscivo).
Most "irregular" verbs become regular in the imperfetto. Venire, tenere, andare, sapere, dovere — all of them take regular endings on a clean stem in the imperfetto: venivo, tenevo, andavo, sapevo, dovevo. The only meaningful exceptions are essere (ero, eri, era, eravamo, eravate, erano), and the short-infinitive verbs that reveal their hidden Latin stems: fare → facevo, dire → dicevo, bere → bevevo, porre → ponevo.
Stress: the loro form is rizotonic
Like the presente, the 3rd-person plural imperfetto is stressed on the root, not the ending. Parlàvano, not parlavàno. Credévano, not credevàno. Dormívano, not dormivàno.
This is a major pronunciation tell. English speakers regularly stress the penultimate syllable (parlavàno), and Italian ears immediately notice. Practice aloud:
- par-LA-va-no ← natural Italian
- par-la-VA-no ← English-influenced and immediately marked
I miei genitori parlavano sempre dei loro viaggi.
My parents always used to talk about their travels.
I bambini credevano alle favole che la nonna raccontava.
The kids used to believe the stories that grandma told.
Da piccoli, dormivano nello stesso letto.
When they were little, they slept in the same bed.
The four core uses
The imperfetto has four interlocking uses, all sharing the underlying logic of "unbounded past."
1. Habitual past
The imperfetto narrates routines and repeated actions in the past. This corresponds to English "used to V" or "would V" (the habitual would, not the conditional).
Da bambino giocavo a calcio tutti i pomeriggi.
As a kid I used to play soccer every afternoon.
Mio nonno fumava la pipa la sera dopo cena.
My grandfather used to smoke a pipe in the evening after dinner.
In estate andavamo sempre al mare con i miei zii.
In summer we always used to go to the seaside with my aunt and uncle.
A vent'anni leggevo molto, anche tre libri al mese.
At twenty I used to read a lot, even three books a month.
The signal words for this use are typically frequency adverbs: sempre, ogni giorno, tutti i lunedì, di solito, spesso, ogni tanto, mai.
2. Ongoing past (action in progress)
The imperfetto describes an action that was in progress at some past moment. This corresponds to English "was V-ing", the past progressive.
Mentre leggevo, squillò il telefono.
While I was reading, the phone rang.
Stavo per uscire quando è iniziato a piovere.
I was about to leave when it started raining.
Cosa facevi alle dieci di ieri sera?
What were you doing at ten o'clock last night?
Mentre cucinavo, ascoltavo la radio.
While I cooked, I was listening to the radio.
This use frequently appears in mentre clauses (while-clauses), where the imperfetto sets up the ongoing background and a different tense (passato prossimo, passato remoto) introduces the punctual event that interrupts it.
3. Description, background, and state
The imperfetto paints the scenery and describes the inner states — what something looked like, how someone felt, what was true — at a past time.
Faceva freddo quella sera, e pioveva senza tregua.
It was cold that evening, and it was raining nonstop.
Quando l'ho conosciuta, aveva i capelli rossi e portava sempre il cappotto verde.
When I met her, she had red hair and always wore a green coat.
Ero stanco, avevo fame, e non sapevo dove dormire.
I was tired, I was hungry, and I didn't know where to sleep.
La casa era enorme, ma sembrava abbandonata.
The house was huge, but it looked abandoned.
This is the imperfetto of emotion, perception, opinion, physical state — verbs like avere, essere, sapere, conoscere, sembrare, sentirsi, pensare, credere strongly favor the imperfetto in past contexts because their meanings are stative rather than punctual.
4. Time, age, weather
The imperfetto is the default for stating the time, the speaker's age, or weather conditions at a past moment.
Erano le tre del mattino quando finalmente sono arrivato a casa.
It was 3 AM when I finally got home.
Avevo vent'anni quando ho lasciato l'Italia.
I was twenty years old when I left Italy.
Faceva caldo, c'era il sole, e tutti erano fuori al parco.
It was hot, sunny, and everyone was out in the park.
The English translations sometimes use a simple past (it was 3 AM, I was twenty), sometimes a progressive (it was raining, the sun was shining) — the imperfetto covers all of these.
Two extra uses you'll hear
Polite requests with imperfetto di cortesia
In shops, cafes, and offices, Italians often soften a request by putting the verb in the imperfetto. This is the imperfetto di cortesia ("imperfect of politeness"). It signals tentativeness and respect.
Volevo un caffè, per favore.
I'd like a coffee, please. (literally: I wanted)
Cercavo il direttore, è in ufficio?
I was looking for the manager, is he in the office?
Volevamo un tavolo per due.
We'd like a table for two.
The literal meaning is past — I wanted, I was looking for — but pragmatically it functions as a softer present-time request. Compare voglio un caffè (direct, can sound brusque) with volevo un caffè (polite, default in Italian shops).
Counterfactual if-clauses (colloquial)
In standard written Italian, counterfactual conditionals require the trapassato congiuntivo + condizionale composto: Se avessi avuto tempo, sarei venuto ("If I had had time, I would have come"). In colloquial speech, however, Italians very commonly replace this whole structure with two imperfetti: Se avevo tempo, venivo.
Se avevo tempo, venivo.
If I'd had time, I would have come. (colloquial — non-standard)
Se lo sapevo, te lo dicevo subito.
If I'd known, I would have told you right away. (colloquial)
Se non era per te, non ce la facevo.
If it hadn't been for you, I wouldn't have made it. (colloquial)
This is non-standard but extremely common — you'll hear it constantly in everyday speech, even from highly educated speakers. The standard form se avessi avuto tempo, sarei venuto is preferred in writing and formal contexts. Both are understood, and the colloquial version is not stigmatized in conversation.
The critical contrast: imperfetto vs passato prossimo
The single most important grammatical distinction in Italian past-tense narration is imperfetto vs passato prossimo. They are not interchangeable — they encode different things about the same event.
- Imperfetto = ongoing, habitual, descriptive. No focus on the endpoint. The action is unbounded in past time.
- Passato prossimo = completed, punctual, with a beginning and end (or at least an end). Focus on the event as a whole.
Consider the same verb in both tenses:
Da piccolo, leggevo molti libri.
As a kid, I used to read a lot of books. (habitual — no endpoint specified)
Ieri ho letto un libro intero.
Yesterday I read a whole book. (one completed event, with implied start and end)
Mentre leggevo il libro, è suonato il campanello.
While I was reading the book, the doorbell rang. (imperfetto for the background, passato prossimo for the punctual event)
The third example is the classic textbook contrast: the imperfetto frames the ongoing situation, the passato prossimo introduces the punctual interruption. English does the same with was reading + rang.
A practical rule of thumb: if you can answer "yes" to "did this happen at a specific point and end?", use passato prossimo. If you can't — if the event was repeated, prolonged, descriptive, or unbounded — use imperfetto.
Common mistakes
❌ Da piccolo, ho giocato a calcio tutti i giorni.
Wrong tense for habit — repeated past actions take the imperfetto, not the passato prossimo.
✅ Da piccolo, giocavo a calcio tutti i giorni.
Correct — habitual past requires the imperfetto.
❌ Mentre ho letto il libro, ha suonato il telefono.
Wrong tense for the background — 'mentre' clauses take the imperfetto for the ongoing action.
✅ Mentre leggevo il libro, ha suonato il telefono.
Correct — leggevo for the ongoing background, ha suonato for the interrupting event.
❌ Ieri sono stato stanco tutto il giorno.
Stylistically off — being tired is a state, not an event with clear boundaries; imperfetto fits better.
✅ Ieri ero stanco tutto il giorno.
More natural — descriptive past state takes the imperfetto.
❌ Loro parlavàno della partita.
Wrong stress — the loro form is stressed on the root: parlàvano.
✅ Loro parlàvano della partita.
Correct — par-LA-va-no, stressed on the second syllable.
❌ Capiscivo poco quando sono arrivato in Italia.
Wrong stem — the imperfetto of capire drops the -isc- and behaves like dormire.
✅ Capivo poco quando sono arrivato in Italia.
Correct — capivo, no -isc- in the imperfetto.
❌ Ho voluto un caffè, per favore.
Too direct — using passato prossimo for a polite request sounds odd; imperfetto is the standard polite form.
✅ Volevo un caffè, per favore.
Correct — imperfetto di cortesia is the natural polite form.
❌ Quando ero giovane, sono andato in Italia ogni estate.
Wrong tense for habit — 'every summer' is repeated, so imperfetto.
✅ Quando ero giovane, andavo in Italia ogni estate.
Correct — habitual repetition takes the imperfetto.
Key takeaways
The imperfetto is the unbounded-past tense — the tool Italian uses for everything ongoing, habitual, descriptive, or stative in the past. Three things to internalize:
The endings are uniform across conjugations (-avo/-evo/-ivo) and the -isco subgroup behaves like the pure -ire group (capivo, not capiscivo). Most "irregular" verbs become regular here. The few real exceptions: essere (ero), fare (facevo), dire (dicevo), bere (bevevo), porre (ponevo).
The loro form is rizotonic: parlàvano, credévano, dormívano. Get the stress right and your imperfetto will sound right.
Imperfetto = unbounded; passato prossimo = bounded. Habits, ongoing actions, descriptions, states, time/age/weather — all imperfetto. Discrete events with clear boundaries — passato prossimo. The two tenses regularly cooperate in the same sentence: imperfetto for the background, passato prossimo for the punctual event.
For the broader picture of Italian past tenses, see tenses overview. For the contrasting "snapshot" tense, study the passato prossimo next. The presente indicativo (see overview) shares many of the conceptual tools — habit vs ongoing action, narrative immediacy — but anchored to the present moment instead of the past.
