  • Rhymes: -i
  • Homophone: si
• Syllabification: sí

Etymology 1

Inherited from Old Spanish sy, from Latin sīc (est).

Particle

sí

1. yes, yeah, (used to respond affirmatively to a question, used both informally and formally)

   Synonyms: (colloquial, Mexico, Guatemala) simón, (colloquial) sip

   Antonyms: no, (colloquial, Mexico) nel

2. Used to give positive emphasis to a verb, which is often replaced. Functions similarly to English do.

   Near-synonym: sí que

   Antonym: no

   "Les gusta el chocolate, ¿verdad?" "A mí sí, pero a él no."

   "You both like chocolate, right?" "I do, but he doesn't."

   No sabemos si es sostenible, pero lo que sí sabemos es que funciona muy bien.

   We don't know if it's sustainable, but what we do know is that it works very well.

Usage notes

• In Spanish, sí can be used to give positive emphasis to a verb, usually when something else is negated in the opposite way. This is translated with English do.

Yo no sé jugar al fútbol, pero tú sí sabes jugar al fútbol.

I don't know how to play soccer, but you do know how to play soccer.

The affirmation can also be put before the negation.

Yo (sí) sé jugar al fútbol, pero tú no sabes jugar al fútbol.

I (do) know how to play soccer, but you don't know how to play soccer.

As in English, we can drop verbs that are unnecessarily repeated.

Yo no sé jugar al fútbol, pero tú sí.

I don't know how to play soccer, but you do.

The same thing can be done when the negation is after the affirmation, leaving just a no, which is translated with don't in English.

Yo (sí) sé jugar al fútbol, pero tú no.

I (do) know how to play soccer, but you don't.

The negation can be implicit:

Esto sí es una fiesta.

This sure is a party. / This is what I call a party. (literally "This IS a party", as opposed to other parties which are not as good)

For words with similar functions in other languages, see French si, Italian sì, Portuguese sim, Dutch wel, Afrikaans wel, and German schon. See also Russian и (i).
