For nouns, the number (whether the
word is singular or plural) works exactly as in English: the singular form is
used when referring to one subject and the plural form when referring to two or
more. But in Italian also adjectives and articles are number-sensitive, whereas
in English they are not: "the old house" in plural form becomes "the old
houses", only the noun changes, while in Italian also the article and the
adjective would be turned in plural form.
Number Inflections for Nouns: There are many rules to obtain the plural of italian nouns; but, generally, the plural is derived according to the following rules:
- For regular masculine nouns that end in -o, the ending changes to -i in the plural. In the
same way regular feminine nouns that end in -a take on -e endings in the
plural. Examples:
| For masculine nouns |
| Singular |
Plural |
English |
|
| fratello |
fratelli |
brothers |
| libro |
libri |
books |
| nonno |
nonni |
grandfather |
| ragazzo |
ragazzi |
boys |
| For Femenine nouns |
| Singular |
Plural |
English |
|
| casa |
case |
houses |
| penna |
penne |
pens |
| pizza |
pizze |
pizzas |
| ragazza |
ragazze |
girls |
- The plural forms of some nouns end in -e will end in
-i (regardless of whether these nouns are masculine or feminine).
| Singular |
Plural |
English |
|
| bicchiere |
bicchieri |
(wine) glass |
| chiave |
chiavi |
keys |
| fiume |
fiumi |
rivers |
| frase |
frasi |
phrases |
- As a particular case, we have the words ending with co, ca, go, ga; these nouns and adjectives add an h to their plural form. Examples:
| Singular |
Plural |
English |
|
| buco |
buchi |
holes |
| fico |
fichi |
figs |
| chirurgo |
chirurghi |
surgeons |
| mucca |
mucche |
cows |
- However, when the vowel that comes before co or go is
i (i.e. ...ico, ...igo), in most cases the masculin plural drops the h, thus
becoming ...-ci or ...-gi (English sound ...chyh or ...jyh). Examples:
| Singular |
Plural |
English |
|
| amico |
amici |
friends |
| nemico |
nemici |
enemies |
| tecnico |
tecnici |
technical |
| comico |
comici |
comical - comedians |
- Nouns ending with an accented vowel or a consonant
(such as words of foreign origin) do not change in the plural, nor do the
abbreviated words.
| Singular |
In plural would be... |
English |
|
| caffè |
due caffè |
Two coffees |
| film |
due film |
Two films |
| foto |
due foto |
Two photos |
- In other cases the plural is a little difficult to recognize for a
beginner; many times is recognized by external indicators, as
articles, pronouns etc. Examples:
| Singular |
Plural |
English |
|
| il tribù |
i tribù |
the tribes |
| la città |
le città |
the cities |
| l'analisi |
gli analisi |
the analyses |
Note: Adjectives follow the same
two patterns as nouns
