Italian Adjetives

Adjectives that end in -e do not need to modify their endings for gender. Their endings change to "i" only depending on whether the noun is singular or plural. Examples:

Il libro verde » the green book
La porta verde » the green door
I libri verdi » the green books
Le porte verdi » the green doors

There are quite a few other exceptions for forming plural adjectives. For instance, adjectives that end in -io (with the stress falling on that i) form the plural with the ending -ii: addio/addii; leggio/leggii; zio/zii. The table below contains a chart of other irregular adjective endings you should know.

Singular Ending	Plural Ending	Singular Ending	Plural Ending
-ca	-che	-ga	-ghe
-cia	-ce	-gia	-ge
-cio	-ci	-gip	-gi
-co	-chi	-glia	-glie
-scia	-sce	-glio	-gli
-scio	-sci	-go	-ghi

Examples:

pacifico pacific (m) » pacifici pacific
pacifica pacific (f) » pacifiche pacific
largo large (m) » larghi large
larga large (f) » larghe large
vecchio old (m) » vecchi old
vecchia old (f) » vecchie old
bianco white (m) » bianchi white
bianca white (f) » bianche white

There are only 3 irregular adjectives: buono (good), bello (beautiful, nice), quello (that). When these adjectives are put in front of their noun, they follow their own rules.
