Hola. Nosotros somos Mercedes, Ramón, Carlos y Juan. Don Fernando es nuestro padre. Nuestra casa se llama "La Gavia."

The top one is the one I guessed, and the bottom is the answer. Can someone explain why I should use nuestro instead of nuestros? I thought the children were the object, and thus the need for the extra s. Also, if looked at in a different view, couldn't "su" be right too?

Answer 1

Grammar.

It's nuestro because you only have one father. You have two parents, so it would be "nuestros padres" in a slightly different sentence.

Answer 2

Also, if looked at in a different view, couldn't "su" be right too?

NO, the subject is nosotros, so only nuestro would be possible, su can only be third person

Answer 3

HI saphire: nuestro agrees with the object in number

padre is only one father, so nuestro padre

nuestros padres
