Spanish Dictionary: translation of cuyo

1. whose, of whom
   mi padre, cuyas costumbres bien conoces, se enojó mucho my father, whose habits you well know, got very angry
2. whose, of which
   una casa cuyos cuartos son inmensos a house whose rooms are immense

Usage Note: cuyo, -ya refers to both persons and things. In number and gender it agrees with the noun it identifies and not with its antecedent mi padre, cuyas costumbres bien conoces, se enojó mucho.
