An adverb is a word that modifies (describes) a verb, an adjective, or another adverb.
Many Spanish adverbs end in -mente, while their English equivalents usually end in -ly.
- Él habla rápidamente. - He speaks quickly.
- Me siento perfectamente bien. - I feel perfectly well.
Adverbs that end in -mente / -ly are usually adverbs of manner: they describe how something is done.
These two adverbs are also adverbs of manner: bien and mal.
- Él habla español muy bien. - He speaks Spanish very well.
- Has escrito mal mi nombre. - You have writen my name wrongly.
But there are many other types of adverbs.
- Adverbs of frequency (a menudo - often, mañana - tomorrow)
- Adverbs of place (aquí -here, cerca - near)
- Adverbs of quantity (mucho - a lot, demasiado - too much, muy - very)
- Adverbs of time (ayer - yesterday, hoy - today)
- Comparative adverbs (más -more, menos -less)
- Interrogative adverbs (cuándo -when, por qué - why)
- Negative adverbs (casi nunca - hardly, ever, nunca -never)
- Superlative adverbs (el más - the most, el menos - the least)
