Adverbs of manner - Los adverbios de modo
Un adverbio de modo modifica un verbo y nos dice algo sobre la manera en
que se realiza la acción. Este tipo de adverbios responde a la
pregunta how? (cómo). Se suele formar añadiendo la terminación -ly a un
adjetivo. los adverbios normalmente van detrás del verbo.

He runs quickly.
Elephants move slowly.
Algunas palabras que acaban en -ly son adjetivos y no adverbios:
She is a lovely person.
He is a friendly man.
Hardly (apenas), rarely (raramente), lately (últimamente)
y recently (recientemente) son adverbios de frecuencia y no de modo, aunque
acaben en -ly.

ADVERBS
Adverbs are words that tell us things about the verb. Adverbs tell us in what
way something happens or in what way someone does something.
Adverbs can describe or modify a verb, an adjective or another adverb
He plays the sax beautifully
Beautifully is an adverb: it describes the verb "play"
These buildings are very tall
Very is an adverb: it modifies the adjective "tall"
He ran incredibly quickly
Incredibly is an adverb: it modifies the other adverb in the sentence "quickly"
As we will see, adverbs frequently end in -ly. Yet, the -ly ending is not a
guarantee that that word is an adverb (many words and phrases not ending in ly have adverbial functions as well)
Examples: words like lovely, lonely, friendly, for instance, are adjectives:
She has a lovely voice
Lunatics are lonely people
Dolphins are friendly creaturas
