In Italian, nouns can be
classified according to the gender, in masculine (maschili)
and feminine (femminili),
and to the number, in singular
(singolari) and
plural
(plurali). The
ending vowel of a noun reveals its gender
and its number.
Usually, nouns that end with
the vowel –O are
masculine (tavolo
=
table,
ragazzo
=
boy)
while nouns that end with the vowel –A are
feminine (sedia =
chair,
mappa =
map).
But there are also nouns that end with –E that can be
masculine or feminine (mare =
sea is a masculine noun, while chiave
= key
is feminine). We can understand the gender of these nouns from the
article placed before or checking on a dictionary.
Now we know that masculine
nouns usually end with –O and feminine nouns end with –A.
However, there are exceptions. So, some nouns that end with –A
are masculine
and some that end with –O are feminine.
Let's see now how to make the
plural of a noun. In Italian, to change the number of a noun from
singular to plural, we must change the ending vowel. Masculine
nouns that end with vowel –O and
–E, in
the plural form end with vowel –I.
Feminine
nouns that end with vowel –A,
in the plural form end with vowel –E, while feminine
nouns that end with –E,
in the plural form end with
vowel –I.
Feminine nouns that end with
–O have the same form in the singular and in the plural.
