Infinitive Verbs - Part 2

Infinitive Verbs - Part 1

An infinitive verb is the plain form of a verb that is not conjugated and often has the word "to" before it. It is good to know the plain or base form of a verb, since that is the form that is typically the main listing for the word in a dictionary. You may hear the infinitive "to sit" conjugated as "sat" or "sitting," but the form of the word you will need if you care to look it up is the infinitive "sit." In standard usage, the infinitive will always be preceded by another verb.
