* Gerund: A gerund is a verb form ending in "-ing" that acts as a noun. (Example: *Running* is good exercise.)
* Participle: A participle is a verb form that acts as an adjective. (Example: The *roaring* lion scared the tourists.)
* Infinitive: An infinitive is the base form of a verb preceded by "to". (Example: I want *to eat*.)
