Adjective or Adverb in Spanish Grammar


It’s not always easy to distinguish between adjectives and adverbs in Spanish grammar. Adjectives describe nouns while adverbs describe verbs, adjectives and other adverbs.

Learn when to use adjectives and when to use adverbs with Lingolia’s simple overview and examples. In the exercises, you can practise what you have learnt.


Los tres ratones Parchís, Bolita y Bellota ordenan rápidamente las carpetas. Parchís y Bolita son más rápidos que Bellota.

Los ratones están felices y nos miran riéndose. Han hecho un buen trabajo. Incluso Bellota, que siempre trabaja más despacio, ha trabajado realmente bien.


Adjective or Adverb

Adjectives describe nouns (What is someone/something one like?) They agree with their corresponding noun in number and gender.

Los ratones están felices y nos miran riéndose.The mice are happy and look at smiling.

What are the mice like? – happy

Han hecho un buen trabajo. They’ve done good work.

How is their work? – good
bueno loses the o before a masculine noun in the singular.

Adverbs describe verbs, adjectives, other adverbs, or entire clauses (How does someone do something? How good/bad/… is someone/something?). We can form adverbs in Spanish by adding the ending -mente.

Han trabajado felizmente.They worked happily.

How did they work? – happily
feliz → felizmente

Han trabajado bien.They worked well.

How did they work? – well
bueno → bien

To Note

The following adjectives often come before the noun and in that case they drop their masculine ending o in the singular: primer(o), mal(o), buen(o), tercer(o).

Tengo un mal día.I’m having a bad day. (adjective)
El ejercicio está mal hecho.The exercise is done badly. (adverb)

Adverbs that look like adjectives

Some Spanish adjectives are used as adverbs with certain verbs. These are known as adverbios adjetivales and can be recognised by their -o ending, which never changes – no matter whether the noun is masculine or feminine, singular or plural. The table below lists the most commonly occurring verbs + adverbs that look like adjectives.

Ella corre rápido/lento.She runs fast/slowly.
Ellos hablan alto/bajo.They speak loudly/softly.
Las chicas se levantan temprano.The girls get up early.
