How to Use Cuyo in Spanish: Meaning, Forms, Examples and More!

Have you ever seen the word cuyo (whose, of which) in Spanish?

Cuyo is not a possessive per se, but it always has something to do with possession.

This word helps us identify possessor and possessed in a sentence and additionally allows us to introduce more information in the form of a relative clause.

While it’s linked to possession, cuyo is actually not a possessive word but a relative adjective.

All About Relative Adjectives like Cuyo in Spanish

Relative adjectives are adjectives that show relation in sentences. They refer back to something or someone that has already been mentioned (the antecedent) and introduce new information about them in the form of a relative clause.

All this sounds way more complicated than it is in reality.

Let’s have a look at one example with our guest star of the day: Cuyo .

Cuyo and its forms always refer back to a person or thing that appears before them in the sentence (this is called the antecedent). Following cuyo is another person or thing.

Its mission in the sentence is to make it clear that the antecedent is the possessor of the second person or thing.

La chica cuyo gato es negro es mi hermana. (The girl whose cat is black is my sister.)

This sentence contains an antecedent (the girl), the relative adjective cuyo (whose) and additional information that can be analyzed like this:

gato (cat) — This is the noun possessed by the girl, who is the owner.

es negro (is black) — This is the new information about the cat.

es mi hermana (is my sister) — This is the new information about the antecedent.

Every sentence with cuyo or one of its siblings (cuya, cuyos and cuyas, all meaning “whose”) will look similar to the previous example. They will always follow this pattern:

antecedent + cuyo + a noun

The new information will normally come at the end of the sentence:

El hombre cuya bufanda es roja es mi padre. (The man whose scarf is red is my father.)

However, we can also have that information at the beginning:

Mi padre es el hombre cuya bufanda es roja. (My father is the man whose scarf is red.)

Either way, both in Spanish and English, the meaning of the sentence is the same: I have a father and he is the man who is wearing a red scarf.

Now that you know what a relative adjective is and how to form sentences with it, let’s get to know cuyo a little better and compare it with English “whose.”

How to Use Cuyo in Spanish: Cuyo vs. Whose

Cuyo and “whose” function very similarly in their respective languages. They both refer to an antecedent and introduce information in the form of a relative clause.

You can observe the parallelisms in these two sentences:

La mesa cuya pata está partida es mía.

The table whose leg is broken is mine.

Of course, not all Spanish sentences and their translations into English will have a one-to-one correspondence, but generally speaking, cuyo and “whose” require the exact same components in their sentences (antecedent, relative, possessed thing/person, new information), so their structures will be very similar most of the time.

There are a couple of differences between the two words, though, and some things to take into account when building sentences with cuyo:

1. While English only has “whose” for all genders and numbers, Spanish has four forms: cuyo (masculine singular), cuya (feminine singular), cuyos (masculine plural) and cuyas (feminine plural). 

Here they are in action:

El niño cuyo libro es verde vive en Madrid. The kid whose book is green lives in Madrid.
El hombre cuya bicicleta está rota vende coches. The man whose bike is broken sells cars.
La mujer cuyos hijos son cocineros acaba de llegar. The woman whose children are cooks has just arrived.
El avión cuyas azafatas son de Miami acaba de aterrizar. The plane whose stewardesses are from Miami has just landed.

2. These four forms always have to agree with a noun (because they are adjectives), but they do not agree with the antecedent! Instead, they agree with the possessed thing or person:

El niño cuyo libro es verde vive en Madrid.The kid whose book is green lives in Madrid.
El hombre cuya bicicleta está rota vende coches.The man whose bike is broken sells cars.
La mujer cuyos hijos son cocineros acaba de llegar.The woman whose children are cooks has just arrived.
El avión cuyas azafatas son de Miami acaba de aterrizar.The plane whose stewardesses are from Miami has just landed.

3. The nouns these relative adjectives agree with will always follow them:

Visitó la casa cuyo dueño es de Venezuela. He visited the house whose owner is from Venezuela.

Not: Visitó la casa dueño cuyo es de Venezuela. (He visited the house owner whose is from Venezuela.)

Now you’re ready to enjoy everything each of these four little words can offer you in Spanish!

I have divided them into four groups just for clarity’s sake.

Believe it or not, you already know everything there is to know about them, so the rest of this post consists mainly of examples. The sentences in each group only contain the corresponding relative adjective, so it will be easier for you to see and understand each of them.
