Adverbs modify verbs or adjectives to describe how an action (verb) is performed, how intense a quality (adjective) is, etc.:
Habla bien. No estudiamos demasiado. Es bastante difícil.
|
She speaks well. (adverb 'well' modifies verb 'speak') We do not study too much.
It's quite difficult. (adverb 'quite' modifies adj. 'difficult') |
• Adverbs have no feminine or plural forms.
Son bastante difíciles. Las peras están demasiado viejas. Me gustan mucho las fiestas.
| They’re quite difficult. The pears are too old. I like parties a lot. |
→ Some adverbs, however, are also adjectives, so they must agree with the noun in number and gender: Tiene muchos problemas, bastantes preocupaciones y demasiadas deudas.
