Riuscire: Full Conjugation

Riuscire (to succeed, to manage to) is morphologically transparent: it is ri- + uscire, "to come out again." Its modern meaning has drifted far from that literal sense — today it expresses succeeding at doing something, managing to do something, or even being able to do something with effort. The literal idea of "coming out (well)" is preserved in expressions like la torta mi è riuscita male ("the cake came out badly for me"), where the verb still feels closer to the uscire root.

Conjugationally, riuscire is uscire with the ri- prefix glued on. Every paradigm is identical, including the famous u/e vowel shift in stressed forms: riesco, riesci, riesce, riusciamo, riuscite, riescono. When the stress is on the stem, the u turns into e (compressing under stress). When it shifts to the ending in noi and voi, the u relaxes back. Auxiliary in compound tenses is essere, exactly like uscire, and the participle agrees with the subject.

What makes riuscire central to natural Italian speech is its mandatory pairing with the preposition a: riuscire a + infinitive. The preposition is not optional — non riesco capire is wrong; only non riesco a capire is grammatical. And once you internalise this pattern, you discover it is one of the most natural ways for Italians to talk about effort, ability, and achievement: anywhere an English speaker would say I can / I'm able to / I manage to, an Italian often says riesco a.

Indicativo presente

The same boot pattern as uscire: four stressed forms with the riesc- stem (io, tu, lui, loro) and two unstressed forms with the riusc- stem (noi, voi). The sc is soft [ʃ] (like English sh) before e or i — riesci, riesce, riusciamo, riuscite — but hard [sk] before o — riesco, riescono. The same verb produces both sounds depending on the following vowel.

The 1sg riesco is one of the most useful single words in Italian conversation. Non riesco is the natural formula for confessing limits — softer than non posso (which sounds like a refusal), more honest than silence.

Imperfetto

The imperfetto is completely regular on the predictable riusc- stem. The vowel shift disappears because stress now falls on the ending throughout. This is the dominant tense for past habits of effort and limit: non riuscivo mai a ("I could never manage to"), riusciva sempre a ("she always managed to").

Passato remoto

A fully regular -ire passato remoto, like uscire. Two double-vowel forms to watch:

• riuscii (1sg) — stem riusc-
  • ending -ii; pronounce both *i*s.
• riuscì (3sg) — with the mandatory grave accent. Without the accent, the form collapses into nothing recognisable. Riuscì = he/she succeeded; riusci with no accent is not a word.

Note the double m in riuscimmo (1pl), distinguishing the historical past from the present riusciamo. This is the same pattern as uscire → uscimmo, finire → finimmo: every regular -ire verb has the double-m in the 1pl passato remoto.

Futuro semplice

The future is fully regular — third-conjugation verbs add the future endings to the infinitive stem, no contraction. No vowel shift here because the stem is unstressed. Mandatory grave accent on the 1sg and 3sg: riuscirò, riuscirà.

The future is the natural tense for promises and predictions about success: Ce la farai / Ci riuscirai — both mean "you'll manage it," but the latter is heavier on the achievement frame.

Condizionale presente

Fully regular conditional. As always, watch the double m in riusciremmo (conditional) versus single-m riusciremo (future). The conditional pairs naturally with hypothetical structures: Riuscirei a finire se non venissero a interrompermi ogni cinque minuti.

Congiuntivo presente

The same u/e shift governs the subjunctive: the four stressed forms (the three singulars and loro) take riesc-, the two unstressed forms (noi and voi) take riusc-. The three singulars collapse into riesca.

The subjunctive of riuscire lives at the intersection of doubt and effort: spero che riesca, temo che non riesca, è importante che riesca. It is one of the most natural triggers for the subjunctive in everyday speech.

Congiuntivo imperfetto

Fully regular -ire imperfect subjunctive on the predictable riusc- stem. Used in hypotheticals (se riuscissimo a partire prima) and after past-tense subjunctive triggers (non pensavo che riuscissi).

Imperativo

The imperative of riuscire is rare in everyday speech — it's hard to command someone to succeed — but it shows up in pep talks and motivational discourse: Riesci! Ce la puoi fare! The forms follow the same u/e shift: stressed riesci, riesca, riescano with riesc-, unstressed riusciamo, riuscite with riusc-.

Forme non finite

The participle riuscito is regular. Because riuscire takes essere as auxiliary, it agrees with the subject in gender and number: riuscito (m.sg.), riuscita (f.sg.), riusciti (m.pl. or mixed), riuscite (f.pl.).

The participle is also a productive adjective: un piano riuscito ("a successful plan"), una giornata riuscita ("a day that turned out well"), un dolce poco riuscito ("a not-so-successful dessert"). Italian uses riuscito/a exactly where English uses successful.

Compound tenses (auxiliary: essere)

Riuscire is an intransitive verb (it cannot take a direct object) and takes essere as its auxiliary, exactly like uscire. The past participle agrees with the subject in gender and number.

Riuscire vs potere — the most important distinction

This is the central choice you face whenever English would say "can." The two verbs answer different questions:

The classic minimal pair:

• Non riesco a dormire. — I can't sleep. (I'm trying, but sleep won't come — insomnia.)
• Non posso dormire qui. — I can't sleep here. (It's not allowed / there's no bed.)

For the systematic comparison, see riuscire vs potere. Once the distinction clicks, your Italian becomes noticeably more native: you stop saying non posso dormire (which an Italian interprets as "I'm not allowed to sleep") and start saying non riesco a dormire — what you actually mean.

Riuscire bene / male — quality of outcome

A second use, closer to the literal "come out" sense: riuscire bene / male / + adjective = "to turn out well / badly / a certain way." Used for cakes, plans, photographs, parties, anything that has an outcome.

Note the dative mi/ti/gli construction in mi è riuscita male — literally "it came out badly to me," the same logic as piacere. The thing is the subject; the experiencer is dative.

Set phrases worth memorising

• riuscire a + infinitive — to manage to do
• riuscire bene / male — to turn out well / badly
• riuscire simpatico/antipatico (a qualcuno) — to come across as nice/unpleasant (to someone)
• non riuscire a credere ai propri occhi — to not believe one's eyes
• un tipo riuscito / una riuscita (noun) — a successful person / a success
• riuscita (noun) — outcome, success

Common mistakes

Key takeaways

Riuscire is uscire with a meaning shift: from "to come out" to "to succeed, to manage to." Conjugationally, the two verbs are identical, including the u/e vowel shift in stressed forms.

Three points to internalise:

1. Always followed by a + infinitive when expressing what you manage to do. Riesco a capire, non riesci a dormire, riuscirà a finire. The preposition is non-negotiable.

2. Auxiliary is essere, with full agreement: sono riuscito, è riuscita, siamo riusciti, sono riuscite. Same pattern as uscire.

3. Riuscire ≠ potere. Riuscire = achieve / manage / succeed (internal effort, ability with effort). Potere = be able / be allowed (external possibility, permission). The most frequent A2 error is producing non posso where Italians produce non riesco a.

The companion verbs are uscire (same paradigm, different meaning) and potere (the verb that splits the English "can" with riuscire). Learn the three together and the entire space of Italian "ability" verbs becomes orderly.
