Italian grammar: Plural of nouns

Plural of nouns in Italian

In Italian, the main difference between a noun in the singular and another one in the plural is in a different ending.

This is the most common form of plural, but not the only one.

In fact, there are also some nouns which have the same form for both the singular and the plural, "Invariable nouns", (nomi invariabili), some other nouns that lack singular or plural, "Defective nouns", (nomi difettivi) and, finally, other nouns which have more than one form for the singular or the plural (nomi sovrabbondanti).
