I would like to know a little bit more about gerunds. Can we use gerunds with all verbs, why are they so important??
See Verb Lists: Infinitives and Gerunds
The gerund's claim to fame, or its importance is its form (what it looks like) and its function (what is does in a sentence).
Gerunds are nouns that end in -ing. They look like verbs, but they are not.
Gerunds sit in the subject or object position of a sentence. That's where all nouns sit.
