Adverbs are words that modify a verb, an adjective, or another adverb. Adverbs can provide additional information about frequency, manner, quantity, place, or time. Adverbs explain when, how, where, how often, or to what degree something is done.
Many adverbs are formed from adjectives, by adding the suffix -mente to the feminine singular form, the same way we add -ly to an adjective in English.
Positioning Spanish Adverbs
When a Spanish adverb modifies a verb, the adverb is placed after the verb.
you speak well
When an adverb is modifying another adverb or an adjective, the adverb is placed before the adverb or adjective it modifies. For example:
escribís* muy bien
ella esta siempre ocupada
you write very well
she is always busy
Adjectives as Adverbs
Many adjectives become adverbs by simply adding -mente. Just like in English when we add -ly to an adjective. For example:
Some adverbs don't have anything to do with adjectives:
aquí (here), bien (well) & despacio (slowly).
