reagire — Italian conjugation

to react

Frequency#680Irregular

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.

PronounItalianEnglish
ioreagiscoI react
tureagisciyou react
lui/leireagiscehe/she/it reacts
noireagiamowe react
voireagiteyou (pl.) react
lororeagisconothey react

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.

PronounItalianEnglish
ioreagiiI reacted
tureagistiyou reacted
lui/leireagìhe/she/it reacted
noireagimmowe reacted
voireagisteyou (pl.) reacted
lororeagironothey reacted

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.

PronounItalian
ioreagivo
tureagivi
lui/leireagiva
noireagivamo
voireagivate
lororeagivano

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?

PronounItalianEnglish
ioreagireiI would react
tureagirestiyou would react
lui/leireagirebbehe/she/it would react
noireagiremmowe would react
voireagiresteyou (pl.) would react
lororeagirebberothey would react

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.

PronounItalianEnglish
ioreagiròI will react
tureagiraiyou will react
lui/leireagiràhe/she/it will react
noireagiremowe will react
voireagireteyou (pl.) will react
lororeagirannothey will react

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.

PronounItalianEnglish
ioho reagitoI have reacted
tuhai reagitoyou have reacted
lui/leiha reagitohe/she/it has reacted
noiabbiamo reagitowe have reacted
voiavete reagitoyou (pl.) have reacted
lorohanno reagitothey have reacted

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.

PronounItalianEnglish
ioavevo reagitoI had reacted
tuavevi reagitoyou had reacted
lui/leiaveva reagitohe/she/it had reacted
noiavevamo reagitowe had reacted
voiavevate reagitoyou (pl.) had reacted
loroavevano reagitothey had reacted

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.

PronounItalian
ioavrei reagito
tuavresti reagito
lui/leiavrebbe reagito
noiavremmo reagito
voiavreste reagito
loroavrebbero reagito

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.

PronounItalianEnglish
ioavrò reagitoI will have reacted
tuavrai reagitoyou will have reacted
lui/leiavrà reagitohe/she/it will have reacted
noiavremo reagitowe will have reacted
voiavrete reagitoyou (pl.) will have reacted
loroavranno reagitothey will have reacted

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.

PronounItalian
ioreagisca
tureagisca
lui/leireagisca
noireagiamo
voireagiate
lororeagiscano

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.

PronounItalian
ioreagissi
tureagissi
lui/leireagisse
noireagissimo
voireagiste
lororeagissero

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.

PronounItalian
tureagisci
lui/leireagisca
noireagiamo
voireagite
lororeagiscano

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.

PronounItalian
tunon reagire
lui/leinon reagisca
noinon reagiamo
voinon reagite
loronon reagiscano
