Adverbs in Spanish are wonderfully easy to form.
Unlike Adjectives (including articles) and nouns, adverbs do NOT need to match in number and gender since they are modifying a verb. Their forms are invariable which means they are non-changing: no worries about gender or number since verbs have neither.
And there are only a few special adverbs.
Adverbs are formed out of adjectives.
Remember that most adjectives in Spanish end in "O" in the masculine singular (default) form. Others end in "e" or a consonant. This affects how an adverb is formed.
Adjectives which end in "o" in the masculine singular form:
We change the adjective to the feminine form and add "mente" :
| Lento | lentA + mente: | lentamente |
| Maravilloso | maravillosA + mente: | maravillosamente |
| Rápido | rápidA + mente: | rápidamente |
Hey! Special Spanish adverb bonus: if the adjective has an accent mark just leave it there!
Adjectives which end in "e" or a consonant in the masculine singular form
We simply add "-mente:
| Diligente + mente: | diligentemente |
| Fácil + mente: | fácilmente |
| Suave + mente: | suavemente |
Exceptions
There are a couple:
- Bien and
Mal: to do something
well or poorly
- This includes the superlatives: Mejor and Peor: to do something better/best or worse/worst
- Mucho and Poco: to do something a lot or to do it very little
