Italian Plurals and Gender: -o, -a, -e and the Exceptions
By Michael McGettrickUpdated 27 September 2026
Italian noun gender has a reputation it has not earned. In German you learn the gender of every noun by rote, because the word itself rarely tells you. In Italian the last letter usually does, and the plural is formed by swapping that one vowel for another. It is one of the most generous systems in any European language, and it stays generous right up until a masculine noun ends in -a and breaks the pattern in public.
This page covers the pattern, the handful of exception families worth knowing by name, and the spelling adjustments that keep the sounds intact. The articles that go in front of all of it (, , and friends) are on Italian articles.
The three-ending system
Nearly every Italian noun ends in a vowel, and the vowel is doing two jobs: it signals the gender and it carries the number.
| singular ends in | usual gender | plural ends in | example |
|---|---|---|---|
| -o | masculine | -i | , i |
| -a | feminine | -e | , case |
| -e | masculine or feminine | -i | , i ; , |
So becomes i , becomes , becomes i , and becomes . Notice that nothing is ever added. There is no -s ending anywhere in Italian, and learners who arrive from Spanish or French keep trying to bolt one on. Italian does it by replacing, not by stacking.
The -e row is the only one that does not tell you the gender. is masculine and is feminine, which is at least intuitive; (flower) and (night) are not. For these, learn the noun with its article, the way you would in German, and let the article carry the gender into memory.
Endings that settle the -e nouns
The -e nouns are not a lottery. A few endings decide the question for whole families:
- -zione is feminine:
l'. Plurals in -i: - - is masculine:
l',i. - -ione in general leans feminine (
l'), with the odd exception such as
Between them, these rules handle a large share of the -e nouns you will meet. The ones left over, like , , , , and , you simply learn with the article attached.
The exceptions worth knowing by name
The system leaks in a few predictable places. These are the families that catch learners, in rough order of how often they will catch you.
Masculine nouns in -a
A group of nouns that came into Italian from Greek end in -ma and are masculine. They take masculine articles and make their plural in -i, not -e:
| singular | plural | meaning |
|---|---|---|
| i | problem |
| i | programme |
| i | system |
This is the exception English speakers hit first, because is one of the commonest words in the language and it looks exactly like . Say la problema and every Italian in the room will notice. The fix is to learn the family as a family: when you see -ma on a word that looks international, suspect a masculine.
papà is masculine for the obvious reason, and it does not change in the plural, because it ends in a stressed vowel (see below).
Feminine nouns in -o
The mirror image is smaller but includes one very common word:
| singular | plural | why |
|---|---|---|
| | a Latin feminine that kept its gender |
radio | radio | short for radiofonia, radiotelegrafia |
| | short for fotografia |
l' | | short for automobile |
is the one to memorise, because it is irregular twice: feminine despite the -o, and plural in -i despite being feminine. The other three are abbreviations of longer feminine words, and they kept the gender of the word they were cut down from while losing the ending that would have told you.
Nouns that never change
Some nouns are invariable: singular and plural are the same word, and only the article moves.
- A stressed final vowel:
i. Almost every noun in a stressed -tà is feminine, which settles its gender too. - A final consonant, which in practice means borrowed words:
film,i film;bar,i bar;computer,i computer;l'hotel,hotel. Italian does not add an English -s, so i films is wrong, however natural it feels. - One syllable:
i. - Shortened words:
- -ie:
The quickest way to hear the plural in these is to listen to the article: film against i film is the whole difference.
A handful of truly irregular plurals
A very small number of nouns do something of their own. L' (man) becomes , which is the only common one you need at this stage. (pair) and (arm) switch to a feminine plural in -a: , . Several body parts behave like (il dito, le dita, finger), and so does l'uovo, le uova (egg), and you meet them one at a time rather than as a rule.
Spelling changes that protect the sound
Italian spelling is phonetic, which creates a small problem in the plural. C and g are hard before a, o and u but soft before e and i, so changing the vowel can change the sound. Italian patches this with an h.
-ca and -ga always keep the hard sound: l', ; , . Without the h, amice would be pronounced with a ch sound, and it would stop being the same word.
-co and -go are split. The reliable half: when the stress falls on the second-to-last syllable, the hard sound usually stays, with -chi and -ghi: , i ; , i ; , i . When the stress falls earlier, the sound usually softens: , i . And then there is l', , and , i , which soften against the rule and are too common to ignore. Learn those two as exceptions and the rule of thumb carries the rest.
- loses an i. When the i is unstressed, the plural keeps only one: , i ; l', ; , i ; l', . When the i is stressed, both survive: , .
-cia and -: when a consonant comes before, the i drops ( , ). When a vowel comes before, it usually stays (camicia, camicie). This one matters mostly for spelling, since the sound is the same either way.
People: pairs, shared forms and mixed groups
Nouns for people often come in masculine and feminine pairs, which follow the endings: , ; , ; , ; , ; , . A few titles in -e take -essa for the feminine: , .
Nouns in -ente and -ante often have one form for both, and only the article changes: , ; , ; , . The same goes for , , a young man or a young woman.
When a group is mixed, the masculine plural wins. I is the boys or the boys and girls; i is the sons or the children; is the uncles or an aunt and uncle together. One man turns a group masculine, and the feminine plural tells you the group is all women.
Gender that changes the meaning
A few nouns exist in both genders with different meanings, so the article is not decoration. fine is the aim or purpose; fine is the end. is a military front; is your forehead. You will not meet many of these, but they are the clearest proof that gender in Italian carries information rather than just ceremony.
Mistakes English speakers make
Adding -s. I libros and le casas are Spanish habits; i films is an English one. Italian swaps the vowel or leaves the word alone.
La problema. The commonest gender mistake in beginner Italian, and the one Italians correct most often. It is , i .
I mani. is feminine, so it is , and any adjective agrees in the feminine: , cold hands.
I città. An invariable noun is still feminine in the plural, so the article is : .
Dropping the h. Amice and barce are spelling errors that are also pronunciation errors, because the h is what keeps the c hard.
What to do next
Learn every noun with its article from the first day, , , , and most of this page will look after itself: the article carries the gender, the last vowel carries the number, and you only have to think hard about the families above. Then go back to Italian articles and check that the plural articles, i, and , come as automatically as the singular ones.
Adjectives agree with all of this in gender and number, which is the next step once the nouns are solid: , case . The subject pronouns page shows the one corner of Italian where gender barely matters, and the Italian course drills plurals on the words you will actually meet.
