Welcome to SpanishDict. You must make an attempt first. - rac1, Jan 27, 2017

You have a model to go by, it should not be that hard to post an attempt, and then we would be glad to correct it and explain more if you don't get it. :) - bosquederoble, Jan 27, 2017

Answer 1

To transform a sentence using a possessive adjective into one that uses "de" to show possession just do as the model suggests.

¿Es su libro? (ellos) Answer: ¿Es el libro de ellos?

What you do is simply replace "su" or whatever possessive adjective with the definite article (in this case "el libro" then write in "de" then the suggested subject pronoun, "ellos."

¿Es su maestra" (ella) becomes, "¿Es la maestra de ella?

It's almost mathematical in nature.

I like the mathematical approach, it is how I learned to keep clauses straight with parentheses. :) - bosquederoble, Jan 27, 2017
