Like gerunds, infinitives are also made by using verbs.
Infinitives are composed of the preposition “to + verb”.
Infinitives represent future or abstract activities that have not yet happened. The following examples may help to clarify this:
The first two examples are actual representations that may happen in the future. The last two examples are abstract ideas that also have not yet happened.
Simply ask the “who or what” question to determine the subject.
