Futuro: Complete Reference

This page is the one-stop reference for Italian's two future tenses. The futuro semplice (parlerò — I will speak) refers to actions yet to happen; the futuro anteriore (avrò parlato — I will have spoken) refers to actions completed before another future point. Both use the same set of irregular stems — and crucially, those stems are also the stems of the condizionale, so the work you do here pays double dividends.

Futuro semplice: regular endings

Italian forms the futuro semplice from a stem (the infinitive minus the final -e, with one twist for -are verbs) plus a single set of endings shared by all three classes.

For -are verbs, the a of the infinitive shifts to e: parlare → parler-. This shift is automatic and exceptionless in regular -are verbs.

The endings — -ò, -ai, -à, -emo, -ete, -anno — are the same for every class. The only thing that changes is the stem. Note the obligatory written accents on the 1sg (-ò) and 3sg (-à) forms; they distinguish the future from look-alike subjunctive or other forms and they are required, not decorative.

The irregular stems, grouped by pattern

Italian's irregular futuro stems fall into three clean families. Learn the pattern, not the individual forms.

Syncopated stems (the -ere vowel drops)

A handful of -ere verbs lose the thematic vowel of their infinitive, so the stem ends in a consonant cluster directly before the ending.

Double-consonant stems (the consonant assimilates to -rr-)

A second group reduces the stem to -rr- — historically, an unstable consonant cluster simplified to a doubled r. These look the most exotic but are extremely common.

Short-stem irregulars (-are verbs that keep the a)

Three high-frequency -are verbs resist the regular -a- → -e- shift and keep the a: dare, fare, stare. Plus essere, which has its own unique stem sar-.

(The infinitive dire comes from Latin dīcere; its stem is the regular dir- — included here for completeness.)

Futuro anteriore: compound formation

The futuro anteriore is built like every other Italian compound tense: futuro semplice of avere or essere + past participle.

Auxiliary selection

The choice between avere and essere in the futuro anteriore is identical to the choice in the passato prossimo. If a verb takes essere in the perfect (motion verbs, change-of-state verbs, reflexives, the copula), it takes essere here too.

Participle agreement

With essere, the participle agrees with the subject in gender and number — exactly as in the passato prossimo (sarà andato vs. sarà andata). With avere, the participle stays invariable unless a direct object pronoun precedes the verb, in which case it agrees with that pronoun.

Temporal clauses: the heart of the futuro anteriore

The futuro anteriore is the natural tense of "by the time…" and "once…" — temporal clauses that order one future event before another. After quando, appena, dopo che, una volta che, finché, Italian uses the futuro anteriore for the earlier action and the futuro semplice for the later one.

This is the precise mirror of English "by the time / once / as soon as" + present perfect. The English sequence ("once I've finished, I'll go") and the Italian sequence ("una volta che avrò finito, andrò") match one-to-one.

Epistemic and modal uses

Both future tenses do double duty as markers of conjecture in present and past — uses that have no direct English equivalent and confuse most learners.

Futuro semplice for present probability

Italians use the futuro semplice to make educated guesses about the present.

The English equivalents are must, probably, I'd guess — never the literal future tense.

Futuro anteriore for past probability

The futuro anteriore plays the same role for the past: an educated guess about a completed action.

This epistemic layer is one of the most useful features of the Italian future system once you internalize it. It replaces a whole register of English hedging with a single grammatical move.

A quick tour of the differences from English

English has two future constructions — will + verb and going to + verb — and uses neither for conjecture. Italian collapses both into one futuro semplice and adds the conjectural reading on top. This means:

• An Italian futuro can be predictive ("it will rain"), schedule-based ("the train will arrive at 8"), or conjectural ("it must be raining now"). Context disambiguates.
• A simple present indicative is also widely used for scheduled future events: "domani parto alle sette" (I leave at seven tomorrow). Italians often pick the present over the future for near, definite plans, especially in speech.
• The English shall distinction (1st-person modal nuance) does not exist in Italian — the futuro is the same for all persons.

Common mistakes

Key takeaways

1. Endings are universal: -ò, -ai, -à, -emo, -ete, -anno, with obligatory accents on 1sg and 3sg.
2. Stems split into three irregular families: syncopated (andrò, avrò), double-consonant (verrò, vorrò), and short-stem (sarò, farò). The same stems serve the condizionale.
3. Compound formation uses futuro of avere/essere + past participle. Auxiliary selection follows passato prossimo rules.
4. Temporal clauses with quando, appena, dopo che take futuro anteriore for the earlier event and futuro semplice for the later one.
5. Epistemic uses — futuro semplice for present probability, futuro anteriore for past probability — are everyday Italian, not bookish exceptions. Learn to hear them.
