Plural of adjectives in Spanish

Welcome to our grammar lesson on how to form the plural of adjectives in Spanish.

Forming the plural of adjectives is very easy, because the rules are clear and the exceptions are few.

In this lesson we’ll divide adjectives into 2 groups: those ending in a vowel, and those ending in a consonant. We will learn how to form the plural of both types.
