comprimere — Italian conjugation
to compress
Indicative
Present (Presente) Regular
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 | comprimo | I compress |
| tu | comprimi | you compress |
| lui/lei | comprime | he/she/it compresses |
| noi | comprimiamo | we compress |
| voi | comprimete | you (pl.) compress |
| loro | comprimono | they compress |
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 | compressi | I compressed |
| tu | comprimesti | you compressed |
| lui/lei | compresse | he/she/it compressed |
| noi | comprimemmo | we compressed |
| voi | comprimeste | you (pl.) compressed |
| loro | compressero | they compressed |
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 | comprimevo |
| tu | comprimevi |
| lui/lei | comprimeva |
| noi | comprimevamo |
| voi | comprimevate |
| loro | comprimevano |
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 | comprimerei | I would compress |
| tu | comprimeresti | you would compress |
| lui/lei | comprimerebbe | he/she/it would compress |
| noi | comprimeremmo | we would compress |
| voi | comprimereste | you (pl.) would compress |
| loro | comprimerebbero | they would compress |
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 | comprimerò | I will compress |
| tu | comprimerai | you will compress |
| lui/lei | comprimerà | he/she/it will compress |
| noi | comprimeremo | we will compress |
| voi | comprimerete | you (pl.) will compress |
| loro | comprimeranno | they will compress |
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 compresso | I have compressed |
| tu | hai compresso | you have compressed |
| lui/lei | ha compresso | he/she/it has compressed |
| noi | abbiamo compresso | we have compressed |
| voi | avete compresso | you (pl.) have compressed |
| loro | hanno compresso | they have compressed |
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 compresso | I had compressed |
| tu | avevi compresso | you had compressed |
| lui/lei | aveva compresso | he/she/it had compressed |
| noi | avevamo compresso | we had compressed |
| voi | avevate compresso | you (pl.) had compressed |
| loro | avevano compresso | they had compressed |
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 compresso |
| tu | avresti compresso |
| lui/lei | avrebbe compresso |
| noi | avremmo compresso |
| voi | avreste compresso |
| loro | avrebbero compresso |
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 compresso | I will have compressed |
| tu | avrai compresso | you will have compressed |
| lui/lei | avrà compresso | he/she/it will have compressed |
| noi | avremo compresso | we will have compressed |
| voi | avrete compresso | you (pl.) will have compressed |
| loro | avranno compresso | they will have compressed |
Subjunctive
Present subjunctive (Congiuntivo presente) Regular
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 | comprima |
| tu | comprima |
| lui/lei | comprima |
| noi | comprimiamo |
| voi | comprimiate |
| loro | comprimano |
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 | comprimessi |
| tu | comprimessi |
| lui/lei | comprimesse |
| noi | comprimessimo |
| voi | comprimeste |
| loro | comprimessero |
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 | comprimi |
| lui/lei | comprima |
| noi | comprimiamo |
| voi | comprimete |
| loro | comprimano |
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 comprimere |
| lui/lei | non comprima |
| noi | non comprimiamo |
| voi | non comprimete |
| loro | non comprimano |
