Here's why:
* Adverbs modify verbs, adjectives, or other adverbs, providing information about how, when, where, or to what extent something happens.
* Verbs describe actions or states of being.
* Infinitives are the base form of a verb preceded by "to," and they can act as nouns, adjectives, or adverbs.
In the phrase "to dance," the infinitive "to dance" acts as a noun, referring to the act of dancing.
For example:
* He loves to dance. (Here, "to dance" is the object of the verb "loves").
