Adverbs respond to the questions how, how much, where, and when. As a part of speech, they modify verbs, adjectives, and other adverbs. In English these words often end in -ly, some examples of which are slowly, quickly, studiously, magnanimously, etc. Perhaps the most common irregular adverb in English is well.
Many adverbs that respond to the question how are formed by adding -mente to the feminine form of an adjective or, if lacking a feminine form, simply to the adjective.
Serio: seria + mente = seriamenteChistoso: chistosa + mente = chistosamente
Leal: leal + mente = lealmente
Other adverbs simply have their own form and must be memorized as such. Some examples are mucho, muy, tan, tanto, bien, mal, despacio, etc.
The following examples show how adverbs perform their functions
within the sentence.
As in the examples above, adverbs normally follow the verb with which they are associated. When they modify adjectives or other adverbs they precede those words.
Ellos caminan rápidamente. (verb + adverb)Chile es un país muy interesante. (adverb + adjective)
Llegamos muy temprano. (adverb + adverb)
