dedurre — Italian conjugation
to deduce, to infer
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 | deduco | I deduce |
| tu | deduci | you deduce |
| lui/lei | deduce | he/she/it deduces |
| noi | deduciamo | we deduce |
| voi | deducete | you (pl.) deduce |
| loro | deducono | they deduce |
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 | dedussi | I deduced |
| tu | deducesti | you deduced |
| lui/lei | dedusse | he/she/it deduced |
| noi | deducemmo | we deduced |
| voi | deduceste | you (pl.) deduced |
| loro | dedussero | they deduced |
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 | deducevo |
| tu | deducevi |
| lui/lei | deduceva |
| noi | deducevamo |
| voi | deducevate |
| loro | deducevano |
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 | dedurrei | I would deduce |
| tu | dedurresti | you would deduce |
| lui/lei | dedurrebbe | he/she/it would deduce |
| noi | dedurremmo | we would deduce |
| voi | dedurreste | you (pl.) would deduce |
| loro | dedurrebbero | they would deduce |
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 | dedurrò | I will deduce |
| tu | dedurrai | you will deduce |
| lui/lei | dedurrà | he/she/it will deduce |
| noi | dedurremo | we will deduce |
| voi | dedurrete | you (pl.) will deduce |
| loro | dedurranno | they will deduce |
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 dedotto | I have deduced |
| tu | hai dedotto | you have deduced |
| lui/lei | ha dedotto | he/she/it has deduced |
| noi | abbiamo dedotto | we have deduced |
| voi | avete dedotto | you (pl.) have deduced |
| loro | hanno dedotto | they have deduced |
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 dedotto | I had deduced |
| tu | avevi dedotto | you had deduced |
| lui/lei | aveva dedotto | he/she/it had deduced |
| noi | avevamo dedotto | we had deduced |
| voi | avevate dedotto | you (pl.) had deduced |
| loro | avevano dedotto | they had deduced |
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 dedotto |
| tu | avresti dedotto |
| lui/lei | avrebbe dedotto |
| noi | avremmo dedotto |
| voi | avreste dedotto |
| loro | avrebbero dedotto |
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 dedotto | I will have deduced |
| tu | avrai dedotto | you will have deduced |
| lui/lei | avrà dedotto | he/she/it will have deduced |
| noi | avremo dedotto | we will have deduced |
| voi | avrete dedotto | you (pl.) will have deduced |
| loro | avranno dedotto | they will have deduced |
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 | deduca |
| tu | deduca |
| lui/lei | deduca |
| noi | deduciamo |
| voi | deduciate |
| loro | deducano |
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 | deducessi |
| tu | deducessi |
| lui/lei | deducesse |
| noi | deducessimo |
| voi | deduceste |
| loro | deducessero |
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 | deduci |
| lui/lei | deduca |
| noi | deduciamo |
| voi | deducete |
| loro | deducano |
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 dedurre |
| lui/lei | non deduca |
| noi | non deduciamo |
| voi | non deducete |
| loro | non deducano |
