There are three types of non-finite verbs : gerunds, infinitives and participles. Look at these examples.

Camping is a non-finite verb. In fact, it is a gerund, i.e., a noun formed from a verb. The giveaway for a gerund is the –ing ending.

To go is a non-finite verb. It is an infinitive, i.e., the base form of a verb. The giveaway for an infinitive is often, but not always, the to before it.

Roasted is a non-finite verb. It is a participle, a type of adjective. There is no real giveaway for a participle, but lots of participles end in -ed and -ing.

Screaming and trying - gerunds
To send - infinitive verb
