Learning Italian means not only memorising new vocabulary, but also understanding whether each noun is masculine or feminine. This is important because gender affects the articles, adjectives, and sometimes even the meaning of a word. In this guide, we’ll look at the main rules, common exceptions, and some practical tips to help you quickly recognise the gender of Italian nouns. At the end, you’ll find a short exercise to test yourself.

The basic rule
Most Italian nouns follow these patterns:
| Ending | Gender | Examples |
|---|---|---|
| -o | Masculine | il libro (the book), il treno (the train), il gatto (the cat) |
| -a | Feminine | la casa (the house), la penna (the pen), la porta (the door) |
| -e | Can be masculine or feminine | il fiore (M – the flower), la notte (F – the night) |
Plural forms
- Masculine: -o → -i (il libro → i libri)
- Feminine: -a → -e (la casa → le case)
- Words ending in -e → -i (il fiore → i fiori / la notte → le notti)
Exceptions to the rule
Some nouns don’t follow the “-o masculine, -a feminine” pattern:
- il problema (masculine)
- la mano (feminine)
- il pianeta (masculine)
- la radio (feminine)
