<human>: I need to know the difference between an infinitive and a gerund. How do I do that?
<bot>: The main difference between an infinitive and a gerund is that an infinitive is a verb form used to express an action or state, while a gerund is a verb form used to express an action or state in progress. An infinitive can be formed by combining an auxiliary verb (e.g., will, can, may, shall) with a verb stem (e.g., walk, run, jump). A gerund is formed by adding -ing to the end of a verb (e.g., walking, running, jumping).
