How to pronounce “Sí”

What it literally means

'Sí' comes from the Latin 'sic', meaning 'thus' or 'so', as in 'it is so'. The accent mark (tilde) separates it from 'si', which means 'if'. The two words sound the same.

How to reply

Grammar: Sí (yes) vs. si (if)

With an accent, 'sí' means 'yes'. Without an accent, 'si' means 'if'. They sound identical, so the accent only matters in writing. Also remember to use 'que' in phrases like 'creo que sí' (I think so) and 'claro que sí' (of course).

Common mistakes

✗ Si, gracias.✓ Sí, gracias.
Without the accent, 'si' means 'if', not 'yes'.
✗ Creo sí.✓ Creo que sí.
Spanish needs 'que' to connect the verb to 'sí' in 'I think so'.
✗ —¿Te gusta el café? —Sí, yo hago.✓ —¿Te gusta el café? —Sí, me gusta.
Spanish has no 'do' helper verb like English, so you repeat the main verb or just say 'sí'.

Culture tip

Spanish speakers often answer yes-no questions by repeating the verb instead of saying only 'sí', for example '¿Vienes?' '¡Vengo!' or '¿Puedes?' 'Sí, puedo.' People often double it ('sí, sí') to show eagerness, or say '¡que sí!' to insist. A quick 'sí' is often paired with a nod. In many countries '¿Sí?' is also a common way to answer the phone or to check someone agrees ('Vamos mañana, ¿sí?').

Questions people ask

Does 'sí' need an accent?
Yes. 'Sí' with an accent means 'yes' and 'si' without one means 'if'. In casual texts people often skip it, but in correct writing you should always include it.
What is a formal way to say yes in Spanish?
'Sí' is already fine in any situation. For extra politeness, use 'sí, por supuesto', 'así es' or 'efectivamente', or add a title: 'Sí, señor' or 'Sí, señora'.
What's the difference between 'claro' and 'por supuesto'?
Both mean 'of course'. 'Claro' is more relaxed and very common in everyday speech, while 'por supuesto' sounds a bit more polite and formal.
How do people say 'yes' or 'okay' in Mexico and Spain?
In Mexico you'll hear 'sale' and 'va' to accept plans, and 'simón' as playful slang. In Spain the go-to word is 'vale'. Plain 'sí' is understood and used everywhere.
