intervenire — Italian conjugation
to intervene
Indicative
Present (Presente) Irregular
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 | intervengo | I intervene |
| tu | intervieni | you intervene |
| lui/lei | interviene | he/she/it intervenes |
| noi | interveniamo | we intervene |
| voi | intervenite | you (pl.) intervene |
| loro | intervengono | they intervene |
Simple past (Passato remoto) Irregular
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 | intervenni | I intervened |
| tu | intervenisti | you intervened |
| lui/lei | intervenne | he/she/it intervened |
| noi | intervenimmo | we intervened |
| voi | interveniste | you (pl.) intervened |
| loro | intervennero | they intervened |
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 | intervenivo |
| tu | intervenivi |
| lui/lei | interveniva |
| noi | intervenivamo |
| voi | intervenivate |
| loro | intervenivano |
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 | interverrei | I would intervene |
| tu | interverresti | you would intervene |
| lui/lei | interverrebbe | he/she/it would intervene |
| noi | interverremmo | we would intervene |
| voi | interverreste | you (pl.) would intervene |
| loro | interverrebbero | they would intervene |
Future (Futuro semplice) Irregular
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 | interverrò | I will intervene |
| tu | interverrai | you will intervene |
| lui/lei | interverrà | he/she/it will intervene |
| noi | interverremo | we will intervene |
| voi | interverrete | you (pl.) will intervene |
| loro | interverranno | they will intervene |
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 intervenuto/a | I have intervened |
| tu | sei intervenuto/a | you have intervened |
| lui/lei | è intervenuto/a | he/she/it has intervened |
| noi | siamo intervenuti/e | we have intervened |
| voi | siete intervenuti/e | you (pl.) have intervened |
| loro | sono intervenuti/e | they have intervened |
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 intervenuto/a | I had intervened |
| tu | eri intervenuto/a | you had intervened |
| lui/lei | era intervenuto/a | he/she/it had intervened |
| noi | eravamo intervenuti/e | we had intervened |
| voi | eravate intervenuti/e | you (pl.) had intervened |
| loro | erano intervenuti/e | they had intervened |
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 intervenuto/a |
| tu | saresti intervenuto/a |
| lui/lei | sarebbe intervenuto/a |
| noi | saremmo intervenuti/e |
| voi | sareste intervenuti/e |
| loro | sarebbero intervenuti/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 intervenuto/a | I will have intervened |
| tu | sarai intervenuto/a | you will have intervened |
| lui/lei | sarà intervenuto/a | he/she/it will have intervened |
| noi | saremo intervenuti/e | we will have intervened |
| voi | sarete intervenuti/e | you (pl.) will have intervened |
| loro | saranno intervenuti/e | they will have intervened |
Subjunctive
Present subjunctive (Congiuntivo presente) Irregular
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 | intervenga |
| tu | intervenga |
| lui/lei | intervenga |
| noi | interveniamo |
| voi | interveniate |
| loro | intervengano |
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 | intervenissi |
| tu | intervenissi |
| lui/lei | intervenisse |
| noi | intervenissimo |
| voi | interveniste |
| loro | intervenissero |
Other forms
Imperative (affirmative) (Imperativo) Irregular
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 | intervieni |
| lui/lei | intervenga |
| noi | interveniamo |
| voi | intervenite |
| loro | intervengano |
Imperative (negative) (Imperativo negativo) Irregular
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 intervenire |
| lui/lei | non intervenga |
| noi | non interveniamo |
| voi | non intervenite |
| loro | non intervengano |
