Plural of adjectives in Spanish – Learn and Practice

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

Forming the plural of adjectives is easy, because the rules are pretty clear. We will divide adjectives into 2 types: those ending in a vowel, and those ending in a consonant.

At the end of the lesson you will find a Quiz and an Exercise to practice.

Plural of adjectives ending in a vowel

1. Adjectives ending in a vowel form their plural by adding -s:

• grande → grandes
• bonito → bonitos
• alta → altas

2. Adjectives about nationality or ethnicity ending in í or ú (with an accent mark) can add -s or -es. Both ways are correct:

• marroquí → marroquís / marroquíes
• hindú → hindús / hindúes

Plural of adjectives ending in a consonant

1. Adjectives ending in a consonant form their plural by adding -es:

• superior → superiores
• genial → geniales

2. If the adjective ends in z, we need to also replace z with c:

• feliz → felices
• atroz → atroces
