crollare — Italian conjugation
to collapse
Indicative
Present (Presente) Regular
The presente covers habits, ongoing situations, and plans about to start — much like English “I study” and “I am studying”. One present tense does both in Italian.
Lavora da casa tre giorni a settimana.
| Pronoun | Italian | English |
|---|---|---|
| io | crollo | I collapse |
| tu | crolli | you collapse |
| lui/lei | crolla | he/she/it collapses |
| noi | crolliamo | we collapse |
| voi | crollate | you (pl.) collapse |
| loro | crollano | they collapse |
Simple past (Passato remoto) Regular
The passato remoto tells a completed, narrative past, especially in the south and in literature. The passato prossimo is the normal spoken past in the north, so you choose register and region, not a difference in time alone.
Quella sera arrivò tardi, senza alibi.
| Pronoun | Italian | English |
|---|---|---|
| io | crollai | I collapsed |
| tu | crollasti | you collapsed |
| lui/lei | crollò | he/she/it collapsed |
| noi | crollammo | we collapsed |
| voi | crollaste | you (pl.) collapsed |
| loro | crollarono | they collapsed |
Imperfect (Imperfetto) Regular
The imperfetto is for incomplete past actions, context, and repeated or habitual situations without a clear end. The passato prossimo, not the remoto, is its usual “event” partner in speech.
Da bambina passavo le estati al mare.
| Pronoun | Italian |
|---|---|
| io | crollavo |
| tu | crollavi |
| lui/lei | crollava |
| noi | crollavamo |
| voi | crollavate |
| loro | crollavano |
Conditional (Condizionale) Regular
The condizionale is for polite “would you…”, first-condition hypotheticals, and reported future from a past point of view. The classic if-chain is se + imperfetto → condizionale.
Potresti alzare un poco la voce?
| Pronoun | Italian | English |
|---|---|---|
| io | crollerei | I would collapse |
| tu | crolleresti | you would collapse |
| lui/lei | crollerebbe | he/she/it would collapse |
| noi | crolleremmo | we would collapse |
| voi | crollereste | you (pl.) would collapse |
| loro | crollerebbero | they would collapse |
Future (Futuro semplice) Regular
The futuro semplice is for predictions and far decisions. In speech you often hear the present (with a time adverb) or a paraphrase, and a famous trick is the futuro di probabilità for a present guess: saranno le tre.
Domani partiremo all'alba.
| Pronoun | Italian | English |
|---|---|---|
| io | crollerò | I will collapse |
| tu | crollerai | you will collapse |
| lui/lei | crollerà | he/she/it will collapse |
| noi | crolleremo | we will collapse |
| voi | crollerete | you (pl.) will collapse |
| loro | crolleranno | they will collapse |
Present perfect (Passato prossimo) Regular
The passato prossimo is the workhorse preterit-like past in the north and in everyday Italian: avere/essere + participle, essere for reflexives, motion, and other change-of-state patterns.
Siamo andati a piedi, poi abbiamo preso l'autobus.
| Pronoun | Italian | English |
|---|---|---|
| io | sono crollato/a | I have collapsed |
| tu | sei crollato/a | you have collapsed |
| lui/lei | è crollato/a | he/she/it has collapsed |
| noi | siamo crollati/e | we have collapsed |
| voi | siete crollati/e | you (pl.) have collapsed |
| loro | sono crollati/e | they have collapsed |
Pluperfect (Trapassato prossimo) Regular
The trapassato prossimo is “further in the past than another past” — the Italian pluperfect. It pairs with a main past clause to mark sequence.
Avevamo già mangiato quando suonò il telefono.
| Pronoun | Italian | English |
|---|---|---|
| io | ero crollato/a | I had collapsed |
| tu | eri crollato/a | you had collapsed |
| lui/lei | era crollato/a | he/she/it had collapsed |
| noi | eravamo crollati/e | we had collapsed |
| voi | eravate crollati/e | you (pl.) had collapsed |
| loro | erano crollati/e | they had collapsed |
Conditional perfect (Condizionale passato) Regular
The condizionale passato is for unreal or missed past results and often appears with se + trapassato prossimo in the protasis.
Avrei accettato, se mi avessero avvisato in tempo.
| Pronoun | Italian |
|---|---|
| io | sarei crollato/a |
| tu | saresti crollato/a |
| lui/lei | sarebbe crollato/a |
| noi | saremmo crollati/e |
| voi | sareste crollati/e |
| loro | sarebbero crollati/e |
Future perfect (Futuro anteriore) Regular
The futuro anteriore says something will already be over before a still-later future, or, like the French, can express a logical guess about a past result.
Entro le cinque, avrà già lasciato l'ufficio.
| Pronoun | Italian | English |
|---|---|---|
| io | sarò crollato/a | I will have collapsed |
| tu | sarai crollato/a | you will have collapsed |
| lui/lei | sarà crollato/a | he/she/it will have collapsed |
| noi | saremo crollati/e | we will have collapsed |
| voi | sarete crollati/e | you (pl.) will have collapsed |
| loro | saranno crollati/e | they will have collapsed |
Subjunctive
Present subjunctive (Congiuntivo presente) Regular
The congiuntivo presente is required after many verbs and fixed phrases of will, fear, purpose, and doubt. Impersonal and semi-impersonal triggers (è importante che) also force the subjunctive mood.
Penso che sia la scelta giusta.
| Pronoun | Italian |
|---|---|
| io | crolli |
| tu | crolli |
| lui/lei | crolli |
| noi | crolliamo |
| voi | crolliate |
| loro | crollino |
Imperfect subjunctive (Congiuntivo imperfetto) Regular
The congiuntivo imperfetto is the past of the congiuntivo system after a past matrix clause and in se + congi. imperf. → condizionale with unreal conditions.
Se avessi più tempo, viaggerei ogni mese.
| Pronoun | Italian |
|---|---|
| io | crollassi |
| tu | crollassi |
| lui/lei | crollasse |
| noi | crollassimo |
| voi | crollaste |
| loro | crollassero |
Other forms
Imperative (affirmative) (Imperativo) Regular
The affirmative imperativo reuses the tu form as 3sg for -are verbs, while other conjugations use the normal tu present. It is the direct command register.
Raccontami com'è andata l'esame.
| Pronoun | Italian |
|---|---|
| tu | crolla |
| lui/lei | crolli |
| noi | crolliamo |
| voi | crollate |
| loro | crollino |
Imperative (negative) (Imperativo negativo) Regular
Negative commands use non + full infinitive in modern Italian, which is a distinctive rule compared to other Romance languages. Polite or indirect “please don’t” can still soften the tone in context.
Non aprire quella finestra, per favore.
| Pronoun | Italian |
|---|---|
| tu | non crollare |
| lui/lei | non crolli |
| noi | non crolliamo |
| voi | non crollate |
| loro | non crollino |
