When should I use possessive pronouns in Italian?

Possessive pronouns in Italian are used to express possession of a specific thing (or person) and they are the equivalent of what in English would be “mine,” “yours,” “his,” “hers,” etc. You must remember that in Italian every grammatical particle (as well as the definite article that precedes it) always agrees with the noun it replaces in number and gender. The gender of the person who speaks does not matter at all. Example: La mia casa è gialla. - My house is yellow. Here, it doesn’t matter whether the person who owns the house is a male or female. All that matters is that the word for “house” in Italian is feminine and singular. Example: La mia casa è gialla. La tua invece è verde. - My house is yellow. Yours is green. Here “tua” refers to the noun “house”, which is feminine and singular, therefore it agrees with it in gender and number.
