Ways to say it
| Spanish | IPA | Note |
|---|---|---|
| cuyo | /ˈkuʝo/ | masculine |
| de quien | /de kjen/ (from spelling rules) | |
| cuyos | /ˈkuʝos/ | masculine, plural |
| cuyas | /ˈkuʝas/ | feminine, plural |
Depending on the context, it can function as a possessive determiner meaning 'whose' or 'of which' or as an interrogative meaning 'of whom'.
Which one should you use?
While cuyo functions as a possessive determiner (whose + noun), de quien is a relative pronoun used to mean 'of whom' without a following noun.

How does it change in a sentence?
The relative pronoun 'cuyo' must agree in gender and number with the noun it precedes (the thing possessed), not the person it refers to. The feminine singular form cuya is used when the possessed object is a feminine singular noun.
How do you pronounce it?
/ˈkuʝo/
What mistakes should you avoid?
English speakers often mistakenly try to make cuyo agree with the person being possessed, rather than the noun that follows it.
Did you know?
- In spoken Spanish, cuyo is so rare that using it in a casual conversation can make you sound like you are reading from a 19th-century novel or a legal document.
- The word cuyo is actually a descendant of the Latin genitive form cuius, which is the possessive form of 'who'.
- Unlike the English 'whose', which is strictly a relative or interrogative pronoun, the Spanish cuyo functions more like a determiner, similar to how 'my' or 'their' functions in a sentence.
