The infinitive form cannot be used as the finite verb of the sentence by itself, but it can be used in combination with modal auxiliary verbs, such as can, shall, will, must, dare, and ought to. The modal auxiliary verbs often describe activities that will occur in the future and the speaker’s opinion or feelings about the activities.
