supporre — Italian conjugation
to suppose
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 | suppongo | I suppose |
| tu | supponi | you suppose |
| lui/lei | suppone | he/she/it supposes |
| noi | supponiamo | we suppose |
| voi | supponete | you (pl.) suppose |
| loro | suppongono | they suppose |
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 | supposi | I supposed |
| tu | supponesti | you supposed |
| lui/lei | suppose | he/she/it supposed |
| noi | supponemmo | we supposed |
| voi | supponeste | you (pl.) supposed |
| loro | supposero | they supposed |
Imperfect (Imperfetto) Irregular
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 | supponevo |
| tu | supponevi |
| lui/lei | supponeva |
| noi | supponevamo |
| voi | supponevate |
| loro | supponevano |
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 | supporrei | I would suppose |
| tu | supporresti | you would suppose |
| lui/lei | supporrebbe | he/she/it would suppose |
| noi | supporremmo | we would suppose |
| voi | supporreste | you (pl.) would suppose |
| loro | supporrebbero | they would suppose |
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 | supporrò | I will suppose |
| tu | supporrai | you will suppose |
| lui/lei | supporrà | he/she/it will suppose |
| noi | supporremo | we will suppose |
| voi | supporrete | you (pl.) will suppose |
| loro | supporranno | they will suppose |
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 supposto | I have supposed |
| tu | hai supposto | you have supposed |
| lui/lei | ha supposto | he/she/it has supposed |
| noi | abbiamo supposto | we have supposed |
| voi | avete supposto | you (pl.) have supposed |
| loro | hanno supposto | they have supposed |
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 supposto | I had supposed |
| tu | avevi supposto | you had supposed |
| lui/lei | aveva supposto | he/she/it had supposed |
| noi | avevamo supposto | we had supposed |
| voi | avevate supposto | you (pl.) had supposed |
| loro | avevano supposto | they had supposed |
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 supposto |
| tu | avresti supposto |
| lui/lei | avrebbe supposto |
| noi | avremmo supposto |
| voi | avreste supposto |
| loro | avrebbero supposto |
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 supposto | I will have supposed |
| tu | avrai supposto | you will have supposed |
| lui/lei | avrà supposto | he/she/it will have supposed |
| noi | avremo supposto | we will have supposed |
| voi | avrete supposto | you (pl.) will have supposed |
| loro | avranno supposto | they will have supposed |
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 | supponga |
| tu | supponga |
| lui/lei | supponga |
| noi | supponiamo |
| voi | supponiate |
| loro | suppongano |
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 | supponessi |
| tu | supponessi |
| lui/lei | supponesse |
| noi | supponessimo |
| voi | supponeste |
| loro | supponessero |
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 | supponi |
| lui/lei | supponga |
| noi | supponiamo |
| voi | supponete |
| loro | suppongano |
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 supporre |
| lui/lei | non supponga |
| noi | non supponiamo |
| voi | non supponete |
| loro | non suppongano |
