Nouns: Gender & Number

Every Italian noun has a gender — masculine or feminine — and a number — singular or plural — and these two features shape almost every other word in the sentence around them. Articles, adjectives, past participles, and even some pronouns all have to agree with the noun they refer to, which means getting gender and number right early on is one of the highest-leverage investments you can make as a beginner. The good news is that Italian nouns follow surprisingly regular patterns: most words ending in -o are masculine (il libro, il tavolo), most ending in -a are feminine (la casa, la pizza), and nouns ending in -e can be either, so you'll need to learn their gender along with the word.

Plurals follow their own neat rules. Masculine nouns typically change -o to -i (libro → libri), feminine nouns change -a to -e (casa → case), and -e nouns become -i regardless of gender (studente → studenti, chiave → chiavi). There are exceptions — words like la mano (feminine despite ending in -o), il problema (masculine despite ending in -a), and invariable nouns like il caffè or la città — but these are a small, memorizable set rather than a wide minefield.

Why does this matter in practice? Because saying il amica instead of l'amica, or una problema instead of un problema, immediately signals that something is off, while getting these small things right makes your speech feel effortless to native ears. Italian also has a handful of tricky nouns that change gender in the plural (il braccio → le braccia, l'uovo → le uova, il dito → le dita), which are worth knowing because they appear in everyday vocabulary. Likewise, nouns ending in -tà (la città, la libertà, l'università) and in -ù (la gioventù) are always feminine and invariable in the plural (le città, le università).

Some nouns also have only one fixed gender regardless of the person they describe — la persona is always feminine even when referring to a man, la guida is feminine even when the guide is male, il soprano is masculine even when the singer is female. Others, like il/la nipote or il/la cantante, use the same form for both genders and rely on the article to signal who's meant. In the exercises that follow, you'll work through identifying gender from endings, building plural forms, handling common exceptions, and combining nouns with the right articles and adjectives. By the end, your instinct for which nouns are masculine and which are feminine will be much sharper.
