Possessive adjectives are used to show ownership or possession. For example: when you say 'this is my pen' - 'my' is a possesive adjective. In Italian, the adjective shows gender and number, and always agrees with the noun. Here are some exapmles to explain:1. questo è la mia penna - this is my pen. (since penna is a feminine singular noun, the possessive adjective is also)2. questi sono i miei libri- these are my books. (since libri is a masculine plural noun, the possesive adjective is too)3. È il tuo letto - It is your bed. (Bed is a masculine singular noun, so the possessive adjective is too)Here is a table to show how the possessive adjective changes based on gender and number:my il mio la mia i miei le mieyour (oftu) il tuo la tua i tuoi le tueyour (ofLei) il Suo la Sua i Suoi le Suehis, her, its il suo la sua i suoi le sueour il nostro la nostra i nostri le nostreyour (ofvoi) il vostro la vostra i vostri le vostreyour (ofLoro)il Lorola Loroi Lorole Lorotheiril lorola loroi lorole loroMain exception to the rule:Family membersWhen talking about a specific singualr family member, such as your mother or your father, the article is dropped.
