interferire — Italian conjugation
to interfere
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 | interferisco | I interfere |
| tu | interferisci | you interfere |
| lui/lei | interferisce | he/she/it interferes |
| noi | interferiamo | we interfere |
| voi | interferite | you (pl.) interfere |
| loro | interferiscono | they interfere |
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 | interferii | I interfered |
| tu | interferisti | you interfered |
| lui/lei | interferì | he/she/it interfered |
| noi | interferimmo | we interfered |
| voi | interferiste | you (pl.) interfered |
| loro | interferirono | they interfered |
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 | interferivo |
| tu | interferivi |
| lui/lei | interferiva |
| noi | interferivamo |
| voi | interferivate |
| loro | interferivano |
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 | interferirei | I would interfere |
| tu | interferiresti | you would interfere |
| lui/lei | interferirebbe | he/she/it would interfere |
| noi | interferiremmo | we would interfere |
| voi | interferireste | you (pl.) would interfere |
| loro | interferirebbero | they would interfere |
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 | interferirò | I will interfere |
| tu | interferirai | you will interfere |
| lui/lei | interferirà | he/she/it will interfere |
| noi | interferiremo | we will interfere |
| voi | interferirete | you (pl.) will interfere |
| loro | interferiranno | they will interfere |
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 | ho interferito | I have interfered |
| tu | hai interferito | you have interfered |
| lui/lei | ha interferito | he/she/it has interfered |
| noi | abbiamo interferito | we have interfered |
| voi | avete interferito | you (pl.) have interfered |
| loro | hanno interferito | they have interfered |
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 | avevo interferito | I had interfered |
| tu | avevi interferito | you had interfered |
| lui/lei | aveva interferito | he/she/it had interfered |
| noi | avevamo interferito | we had interfered |
| voi | avevate interferito | you (pl.) had interfered |
| loro | avevano interferito | they had interfered |
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 | avrei interferito |
| tu | avresti interferito |
| lui/lei | avrebbe interferito |
| noi | avremmo interferito |
| voi | avreste interferito |
| loro | avrebbero interferito |
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 | avrò interferito | I will have interfered |
| tu | avrai interferito | you will have interfered |
| lui/lei | avrà interferito | he/she/it will have interfered |
| noi | avremo interferito | we will have interfered |
| voi | avrete interferito | you (pl.) will have interfered |
| loro | avranno interferito | they will have interfered |
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 | interferisca |
| tu | interferisca |
| lui/lei | interferisca |
| noi | interferiamo |
| voi | interferiate |
| loro | interferiscano |
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 | interferissi |
| tu | interferissi |
| lui/lei | interferisse |
| noi | interferissimo |
| voi | interferiste |
| loro | interferissero |
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 | interferisci |
| lui/lei | interferisca |
| noi | interferiamo |
| voi | interferite |
| loro | interferiscano |
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 interferire |
| lui/lei | non interferisca |
| noi | non interferiamo |
| voi | non interferite |
| loro | non interferiscano |
