Learn Italian: Questo è il mio nome e il mio indirizzo.

In Italian, you almost always need to put a definite article (like il, la, i, le) before a possessive word. While in English you just say "my name", in Italian you literally say "the my name" (il mio nome).

I know indirizzo is masculine because it ends in -o, but why does nome use il mio when it ends in -e?

Nouns ending in -e in Italian can be either masculine or feminine. You just have to memorize their gender as you learn them! Nome happens to be masculine, which is why it uses the masculine article il and the masculine possessive mio.

The word indirizzo starts with a vowel. Shouldn't it use the article l' instead of il?

If you were just saying "the address", you would indeed use l'indirizzo. But here, the word mio comes between the article and the noun. Because mio starts with a consonant, the article changes to match it, giving us il mio indirizzo.

In English I can say "my name and address". Do I have to repeat il mio both times in Italian?
