Cuyo is used to indicate the noun which is the object of the clause that follows it. Cuyo is relative because it introduces a relative clause, and an adjective because it must be followed by a noun. Note that cuyo has a possessive value as well. Esa casa, cuya puerta es amarilla, es muy bonita.

How do you use Cuyo in Spanish?

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 singular). Here they are in action: El niño cuyo libro es verde vive en Madrid. (The kid whose book is green lives in Madrid.)

How is quienes used?

Quien means who (or whom) and can only refer to a person, not an animal, nor a place, idea, or thing. 2. Quien needs to match its antecedent (the “who” it refers to) in number. If the antecedent is singular, you use quien; if it is plural, you use quienes.
