There are no (‘s) in Spanish, so we can to take “the long way around”
Instead of “Dad’s hat,” we say “the hat of Dad” (la gorra del padre). Instead of “Adela’s penguin,” we say “the penguin of Adela” (el pinguino de Adela).
2. Or we can use possessive adjectives:
To say: his, her, my, yours, ours, etc, we use this chart:
Mi(s) Nuestro/os, Nuestra/as
Tu(s)
Su(s) Su(s)
Ex:
I want my shirt= Quiero mi falda. I want my shirts= Quiero mis faldas
He uses his book= él usa su libro. He uses his books= él usa sus libros.
