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:
|Singular Ending||Plural Ending||Singular Ending||Plural Ending|
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.
