In grammar, the infinitive is a verb form that shares no finite characteristics of a noun, usually not distinguished person, time or number, but for example in Portuguese is conjugated as person and number. It is a suitable way to express the idea of an action as a general notion, without specifying the circumstances of your particular embodiment (how, when, what or whom).
