While Italian uses many of the same letters as English, the vowels may have little decorations that can make them look and sound very different. In Italian, accents are essential: they’re there for a reason, so you must include them when writing.
If you want to read and write in Italian, one of the first things you should learn is the Italian alphabet, which has 21 letters. You know them all from the English alphabet but they are pronounced differently, so take a moment to learn the Italian alphabet.
In Italian, consonants can be divided into pure and impure sounds (or simple and complex sounds). While both types can occur anywhere in a word, they only really matter, grammatically speaking, at the beginning of masculine nouns.
