Questions & Answers about Il libro non è nuovo, ma è molto bello.
The translation says "but". How does ma work in this sentence?
Where is the word for "it" in the second half of the sentence?
There isn't one! In Italian, you usually drop subject pronouns (like "it", "I", or "you") when it is obvious from the context. Since we just mentioned il libro, the second è (is) automatically implies "it is".
Why do nuovo and bello both end in -o?
