Nouns: gender and number
A1 Il genere e il numero dei nomi 2 / 53
In short
Every Italian noun is masculine or feminine, and its last letter usually tells you which: -o is masculine, -a is feminine, -e can be either. The plural is a vowel swap, not an added -s: -o -> -i, -a -> -e, -e -> -i.
The rule
Italian has no neutral gender and no plural -s. Instead the final vowel carries both pieces of information at once, and it changes when the noun goes plural. Because the article and every adjective must agree with the noun, learn each word with its article: not libro but il libro.
Step 1 - Read the ending for the gender.
- -o -> masculine: il libro, il tavolo, il ragazzo.
- -a -> feminine: la casa, la penna, la ragazza.
- -e -> either one; you must learn it. il padre (father) and la madre (mother) look identical at the end - only the article separates them.
Two endings inside the -e group are reliable and worth banking now: -zione and -sione are always feminine (la stazione, la televisione), and -ore is masculine (il colore, il dottore).
Step 2 - Swap the final vowel for the plural.
- -o -> -i: il libro -> i libri.
- -a -> -e: la casa -> le case.
- -e -> -i, whatever the gender: il padre -> i padri, la madre -> le madri.
Notice the trap built into this system: le case is plural, but the same -e is the singular mark of il padre. The ending alone is never enough - read it together with the article.
Step 3 - Keep the sound: -ca / -ga / -co / -go. This is the c/g rule from the pronunciation guide doing its job. c and g are hard before a, o, u but soft before e, i - so a plural ending in -i or -e would silently soften them. An h is inserted to stop that.
- Feminine -ca -> -che, -ga -> -ghe. Always. l’amica -> le amiche, la banca -> le banche, la riga -> le righe. The hard sound is always preserved.
- Masculine -co / -go: it depends, and the stress decides most cases. If the stress falls on the second-to-last syllable, the sound stays hard: il fuo-co -> i fuochi, il la-go -> i laghi, il par-co -> i parchi. If the stress falls further back, the sound goes soft: il me-di-co -> i medici, il tec-ni-co -> i tecnici.
- Four rebels are stressed on the second-to-last syllable but go soft anyway - learn them as words: amico -> amici, nemico -> nemici, greco -> greci, porco -> porci.
So the pair the whole lesson turns on is l’amico -> gli amici (soft) against l’amica -> le amiche (hard). Same word, different gender, different fate.
Step 4 - Two irregulars you meet on day one.
- la mano -> le mani. Feminine despite the -o, and its plural is -i, not -e. Both halves are irregular.
- l’uomo -> gli uomini. The stem itself changes. La donna -> le donne is perfectly regular next to it.
Forms & patterns
The master table - gender and plural in one:
| Singular ending | Gender | Plural | Example |
|---|---|---|---|
| -o | masculine | -i | il libro -> i libri |
| -a | feminine | -e | la casa -> le case |
| -e | masculine | -i | il padre -> i padri |
| -e | feminine | -i | la madre -> le madri |
Nouns in -e: the article is your only clue.
| Masculine | Feminine |
|---|---|
| il fiore (flower) | la chiave (key) |
| il mare (sea) | la notte (night) |
| il pane (bread) | la neve (snow) |
| il nome (name) | la classe (class) |
| il dottore (doctor) | la stazione (station) |
Hard or soft? The c/g alternation:
| Singular | Plural | What the sound does |
|---|---|---|
| l’amica | le amiche | stays hard - h added |
| la banca | le banche | stays hard - h added |
| la riga | le righe | stays hard - h added |
| il fuoco | i fuochi | stays hard - h added |
| il lago | i laghi | stays hard - h added |
| l’amico | gli amici | goes soft - no h |
| il medico | i medici | goes soft - no h |
The two day-one irregulars:
| Singular | Plural | Note |
|---|---|---|
| la mano | le mani | feminine despite the -o; plural in -i |
| l’uomo | gli uomini | the stem changes |
Examples
- Il libro è nuovo. - The book is new.
- La casa è grande. - The house is big.
- Il padre e la madre parlano italiano. - The father and the mother speak Italian.
- Le chiavi sono qui. - The keys are here.
- Ho due amici italiani. - I have two Italian friends.
- Ho due amiche italiane. - I have two Italian friends (women).
- I medici lavorano molto. - The doctors work a lot.
- I laghi italiani sono belli. - The Italian lakes are beautiful.
- Le mani sono fredde. - The hands are cold.
- Gli uomini parlano con le donne. - The men are talking with the women.
Common mistakes
- le amice -> le amiche - a feminine -ca always keeps its hard sound, so the plural needs the h.
- gli amichi -> gli amici - amico is the famous rebel: the masculine goes soft even though amica stays hard.
- le madre -> le madri - an -e noun takes -i in the plural whatever its gender; only the article stays feminine.
- i mani -> le mani - mano is feminine despite the -o, so the article is le, not i.
- gli uomi -> gli uomini - the plural of uomo is irregular and has to be memorised whole.
Tips
- Store every noun with its article (il / la), the way a dictionary does. For -o and -a words it is a safety net; for -e words it is the only information you get.
- The h is a spelling device, not a grammar one - it exists purely to keep the c or g hard, exactly as in the pronunciation guide. Feminines are the safe side (-ca / -ga always become -che / -ghe); only the masculines make you stop and think.
- Say the singular out loud and find the stress: fuo-co (near the end) -> fuochi; me-di-co (further back) -> medici. Then add the four exceptions - amico, nemico, greco, porco - as vocabulary.
- Mano and uomo are two of the most common nouns in the language and both are irregular. Learn le mani and gli uomini now, as whole words, and you are done with them.
