Catalan does not need a louder synonym of yes to contradict someone forcefully. It normally puts the affirmative adverb sí before que and a complete clause: Sí que vindrà! means “He is coming!” or “He will come, actually!” The related frame prou que + clause means “indeed,” “certainly,” or “very well,” often with the implication that the fact should already be obvious.
These are ordinary pieces of spoken Catalan, not decorative exclamations. Their force comes from the whole stored frame, its word order, and its prosody. English usually expresses the same correction through stress on an auxiliary—“She does know”—whereas Catalan places the emphatic material at the beginning.
The two core patterns
| Pattern | Core function | Typical register | Example |
|---|---|---|---|
| Sí que + finite clause | Contradict a negative assumption or confirm emphatically | neutral; very common in conversation | Sí que ho sap! |
| Prou que + finite clause | Assert “indeed / certainly,” often against doubt or belated denial | neutral to emphatic; especially vivid in speech and narrative | Prou que ho sabia! |
| Topic + sí/prou que + clause | Contrast one person or thing with another | neutral | La Joana sí que hi vindrà. |
| Que sí! | Insist on a previous yes; a response fragment | informal when repeated sharply | Que sí, que ja vinc! |
The accent matters. Sí with an acute accent is the affirmative “yes”; si without one is normally the conditional conjunction “if” or the noun for the musical note B. The page title names the construction, but the construction itself is written sí que.
—La Núria no se'n recordarà. —Sí que se'n recordarà: ho té apuntat al calendari.
—Núria won't remember. —She will remember: she has it in her calendar.
Prou que t'ho vaig advertir, però no em vas voler escoltar.
I certainly warned you, but you wouldn't listen to me.
Sí que: correcting the conversational record
Use sí que when a previous statement, an implication, or the listener’s behavior suggests a negative answer and you want to replace it with a positive one. The contradicted negative does not have to be spoken aloud.
No et pensis que m'he oblidat del sopar: sí que hi vindré.
Don't think I've forgotten about dinner: I really am coming.
Aquest abric sí que abriga; l'altre era massa prim.
Now this coat really is warm; the other one was too thin.
In the second example, there is no explicit “This coat is not warm.” The contrast with l'altre is enough to create the assumption that sí que corrects. This is why translating it mechanically as “yes that” fails: the phrase has discourse scope over the whole following clause.
The finite verb stays in ordinary declarative order. Catalan does not invert the verb and subject as English sometimes does in marked prose. An overt subject may come before sí que as a contrastive topic, or in its ordinary postverbal position when that is natural.
La directora sí que ens va respondre de seguida.
The head teacher did reply to us straight away.
Sí que ha canviat, aquest barri!
This neighborhood really has changed!
That final detached noun phrase, aquest barri, identifies or reinforces an already recoverable topic. The comma reflects the intonational break. It is expressive, but it is not obligatory: Aquest barri sí que ha canviat is the unmarked alternative.
Clitics stay with the verb
Object and adverbial clitics do not attach to sí, prou, or que. They occupy their normal preverbal position inside the finite clause:
sí/prou + que + clitic cluster + finite verb
Sí que me'n recordo, d'aquell cafè de Girona.
I certainly remember that café in Girona.
Prou que els l'hauria deixat, si l'hi haguessin demanat bé.
She certainly would have lent it to them if they had asked her properly.
The second example is intentionally dense: els l'hauria deixat keeps the recipient and direct-object clitics in the same place they would occupy without emphasis. At A2, the practical lesson is simple: learn the outer frame sí que / prou que, then insert an otherwise ordinary clause after que. Do not freeze or delete a clitic just because English has none.
Prou que: “indeed,” not “enough”
Outside this construction, prou normally expresses sufficiency: Ja en tinc prou (“I have enough”), És prou gran (“It is big enough”). In prou que + clause, however, it acts as an emphatic assertion. Its literal association with sufficiency has developed into something like “there is evidence enough to affirm this.” The idiomatic result is “indeed,” “certainly,” or “very well.”
—Potser no ho entenien. —Prou que ho entenien; senzillament, no hi estaven d'acord.
—Perhaps they didn't understand it. —They understood it perfectly well; they simply didn't agree.
Prou que voldria ajudar-te, però avui no puc sortir de la feina.
I certainly would like to help you, but I can't leave work today.
That last sentence often carries a concessive undertone: willingness is real, yet another circumstance blocks the result. Context supplies the contrast; prou que itself remains affirmative.
Prosody: where the correction lives
In a direct contradiction, sí normally receives a strong pitch accent: SÍ que vindrà. The rest of the clause commonly falls toward the end. Prou likewise carries an early emphatic peak, though a speaker can add a second focus on the corrected constituent: PROU que vindrà DIUMENGE.
Exclamation marks are appropriate when the utterance is genuinely forceful, but they are not built into the grammar. A calm written correction can end in a full stop:
Sí que disposem de la documentació; la vam enviar el 14 de maig.
We do have the documentation; we sent it on 14 May. (formal)
In emails and administrative prose, sí que is possible, but formal alternatives such as efectivament, certament, or an unmarked affirmative clause may sound less confrontational. Prou que is more voice-rich and therefore less usual in an impersonal report.
Three frames you can reuse
- Sí que + present/past/future clause: Sí que funciona / va funcionar / funcionarà.
- Prou que + clause, però...: Prou que hi aniria, però treballo.
- Contrastive topic + sí que + clause: Aquest tren sí que para a Sants.
These slots are flexible because the tense and the verb belong to the following clause. What is fixed is the sequence sí que or prou que. Compare the literal but nonidiomatic word-by-word attempt Yes that she comes with idiomatic English “She is coming”; Catalan is not copying English word order but using its own emphatic construction.
Spanish also has sí que, so Spanish can help a learner recognize the broad function. It cannot choose the Catalan clitics or combinations: Catalan says sí que hi anirem, sí que en tenim, and sí que me'n recordo. Importing Spanish allí, de eso, or Spanish clitic order changes the Catalan sentence rather than completing the frame.
Mini-dialogue
—No crec que l'Èric sàpiga arreglar-ho. —Prou que en sap, d'electricitat. —Però avui no vindrà. —Sí que vindrà; m'acaba d'escriure. —Ah, doncs retiro el que he dit.
—I don't think Èric knows how to fix it. —He certainly knows about electricity. —But he isn't coming today. —He is coming; he has just messaged me. —Oh, then I take back what I said.
The exchange shows the different jobs clearly. Prou que en sap rejects an underestimate of ability; sí que vindrà directly reverses a negative prediction. Neither expression is a free-standing interjection like ostres! If you need only an emotional cry, see Interjections and Response Cries. Using prou que as a cheerful toast or solemn proverb in an unrelated social setting would sound incoherent because it expects an asserted proposition after it.
Common Mistakes
❌ Si que vindré demà.
Incorrect for emphatic affirmation: si without an accent means ‘if.’
✅ Sí que vindré demà.
I really am coming tomorrow.
❌ Sí que recordo d'aquella casa.
Incorrect: recordar is transitive here; with recordar-se de, the pronominal verb and en-clitic are required.
✅ Sí que me'n recordo, d'aquella casa.
I certainly remember that house.
❌ Prou que vaig t'ho advertir.
Incorrect clitic placement: t'ho must precede the finite auxiliary vaig.
✅ Prou que t'ho vaig advertir.
I certainly warned you about it.
❌ Sí que ho ella entendrà.
Incorrect word order: a subject cannot interrupt the preverbal clitic and its verb.
✅ Ella sí que ho entendrà.
She, for her part, really will understand it.
Key Takeaways
- Write sí que with an accent when it emphatically affirms or contradicts: Sí que és veritat.
- Use prou que + clause for “indeed / certainly,” not for the ordinary quantity meaning “enough.”
- Keep normal Catalan clause structure after que, including preverbal clitics: sí que n'hi ha, prou que t'ho vaig dir.
- A contrastive topic can precede the frame: La Marta sí que ho entén.
- Strong falling prosody makes the correction sound forceful; a full stop and measured wording can make sí que suitable in careful prose.
