Questions & Answers about Il tuo vestito nuovo è nell'armadio.
Why is it nell'armadio instead of in l'armadio?
When the preposition in (in) is followed by a definite article, they merge into one word. Because armadio (wardrobe) starts with a vowel, it uses the article l'. When you combine in + l', it becomes nell'.
Why do we say il tuo vestito instead of just tuo vestito for "your dress"?
In Italian, possessive words like tuo (your) almost always need a definite article (like il, la, etc.) in front of them. You literally say "the your dress". The main exception is when you are talking about singular family members, like mio padre (my father).
Why does the word nuovo come after vestito?
Wait, vestito means "dress"? It looks like "vest"!
Yes, this is a classic "false friend"! Vestito means "dress" or "suit". If you want to talk about a vest, you would use a word like gilet.
