An infinitive is a verb form that acts as other parts of speech in a sentence. It is formed with to + base form of the verb. Ex: to buy, to work.
A gerund is a verb in its ing (present participle) form that functions as a noun that names an activity rather than a person or thing. Any action verb can be made into a gerund.
