Ways to say it

These terms are used to express agreement or to say 'yes'.

/ˈsi/

Spanish speakers sometimes use sí to mean 'no' when answering a negative question. If asked No vas? ('You're not going?'), saying Sí means 'Yes, I am going'.
The Spanish word sí is a linguistic 'chameleon' because it is also the word for 'himself', 'herself', 'itself' or 'themselves' depending on the context.
The word sí actually shares its roots with the English word 'self' because it stems from the Latin 'sibi', meaning 'to oneself'.
