What is the possessive pronoun in Latin?

The possessive pronoun is translated as 'my' 'your' 'his' 'their' etc in English, and can be easily confused with the personal pronoun in Latin - especially with regards to 'ego, me' etc (the personal pronoun I/me) and 'meus, mea, meum' etc (the possessive pronoun for the 1st person). The main difference is that the personal pronouns function as nouns in a sentence - with their own paradigms that must therefore be learned - and that possessive pronouns are adjectives, and generally decline like an adjective in the same style as 'bonus, bona, bonum'.
