If you see an Italian word that ends in ‑ore, like rumore, you can be pretty sure it’s a masculine noun. Keep also in mind that ‑e words usually end in ‑i in plural.
And don’t forget that rumore means noise, not rumor!
In Italian, gli has a very special sound. It almost sounds like lyee or like ll in the word tortilla, but stronger.
And when gli is not at the beginning of a word, it sounds even stronger!
This only happens before i! Anywhere else, gl sounds just like it does in English, like in inglese or globale.
You'll notice that in Italian many words used for talking about abstract concepts end in ‑ine. These nouns are usually feminine.
Like most ‑e words, the plural forms of these nouns end in ‑i.
