Condizionale: Complete Reference

This page is the full reference for the Italian condizionale. If you've already worked through the overview, regular formation, irregular stems, and condizionale passato, this is where you come to look things up. Conjugation tables, the high-frequency forms list, and a tour of every use the mood serves in real Italian — all in one place.

The endings: identical for all three conjugations

The single biggest mercy of the condizionale presente is that the endings are the same for -are, -ere, and -ire verbs. Once you know them, you know them.

The stem is the future stem, not the infinitive. -are verbs change the a to e (parlare → parler-), -ere verbs drop the final e (credere → creder-), and -ire verbs do the same (dormire → dormir-). Master the future stem and you have the conditional stem for free — this is the half-the-work-for-twice-the-result move that pays back the rest of your Italian study.

Regular conjugation: parlare, credere, dormire

Irregular stems: the same set you learn for the future

Roughly fifteen high-frequency verbs share an irregular stem between future and conditional. Memorize this list once and you cover the great majority of irregular conditional forms you'll meet.

For the full treatment of why these stems behave the way they do, see irregular stems.

Condizionale passato: avere or essere + past participle

The compound conditional is built from the conditional of the auxiliary (avere or essere) plus the past participle. Choice of auxiliary follows the same rules as the passato prossimo: most verbs take avere, but motion verbs, change-of-state verbs, and reflexives take essere.

Participle agreement — the rule in one breath

When the auxiliary is essere, the past participle agrees with the subject in gender and number: Maria sarebbe andata, i ragazzi sarebbero andati. When the auxiliary is avere, the participle is normally invariable (avrei mangiato) — except when a direct-object pronoun precedes the verb, in which case the participle agrees with that pronoun: l'avrei mangiata (referring to la pizza).

The six uses — what the condizionale actually does

The condizionale is a single mood, but Italians use it for six distinct communicative jobs. They all share one quality: the speaker is distancing themselves from the bald assertion of fact.

1. Politeness — softening requests and offers

The naked indicative — voglio un caffè, chiudi la finestra — sounds rude in Italian unless context already makes it clear you're not bossing the listener around. The condizionale is the everyday register of polite interaction.

2. Hypothetical reasoning — what would happen if

This is the use that pairs with the imperfect subjunctive in se clauses — the so-called second conditional in English grammars. Se avessi tempo, finirei il libro.

3. Future-in-the-past — what would happen later

This is the use that surprises English speakers most: in indirect speech reporting a past statement about a later event, Italian uses the condizionale passato, not the present conditional. English uses would (an old past form of will); Italian uses what is structurally a perfect conditional. Worth a separate page in its own right — see passato formation.

4. Rumor and unconfirmed reporting — the journalistic use

Italian newspapers and TV news lean heavily on this construction to flag information they haven't confirmed. There is no clean English equivalent — translation usually has to insert reportedly, allegedly, or is said to have.

5. Hedging an opinion — distancing yourself from your own claim

A speaker who chooses direi over dico is taking the edge off — leaving room for the listener to disagree without making the conversation a confrontation.

6. Wishes and dreams — actions in an imagined world

This use is essentially the second conditional with the se clause omitted — (se potessi) mi piacerebbe vivere in Sicilia. The unspoken hypothetical is implied.

The top twenty conditional forms you'll actually use

The Pareto principle bites hard here. Roughly twenty conditional forms cover the lion's share of what you hear in spoken Italian. Memorize these to recognition speed and your comprehension jumps a level.

Key takeaways

The condizionale presente uses one set of endings (-ei, -esti, -ebbe, -emmo, -este, -ebbero) attached to the future stem. Master the future stem inventory and you've mastered the conditional stems for free.

The condizionale passato is built with the conditional of avere or essere plus the past participle, with the same auxiliary choice and agreement rules as the passato prossimo.

The mood serves six purposes — politeness, hypothesis, future-in-past, hearsay, hedging, and wish — but they share a unifying logic: the speaker is stepping back from a flat assertion of fact. Once you hear the condizionale as a tool for managing the social and epistemic stance of the sentence, it stops being a chunk of grammar to memorize and starts being a register to inhabit.
