6. Los infinitivos
An infinitive (el infinitivo) is the most basic verb form in all languages.
In English, it is always preceded by "to," as in "to run," "to love," and "to travel."
In Spanish, infinitives consist of only one word and are separated into three different conjugations according to their endings:
-ar, -er, or -ir.
These endings are attached to the root of a verb to form the whole infinitive
hablar, correr, compartir
Verbs in the infinitive form indicate what the action is but nothing about who is doing the action at what point in time.
