I know how to use possessive pronouns in Russian:
Это моя книга.
I also know how to describe a person's possession:
Это книга подруги.
But how do I combine two persons, such as in this example:
I want to give this book to my girlfriend's mother.
I don't know what to search for. How is this called in linguistic terms?
Which linguistic cases do I use here for the words
My guess would have been:
Я хочу подарить эту книгу маме моей подруги (на Рождество).
