1. Participle

2. Gerund

3. Infinitive

Explanation:

a) The three verbals— gerunds, infinitives, and participles—are formed from verbs, but are never used alone as action words in sentences. Instead, verbals function as nouns, adjectives, or adverbs. These verbals are important in phrases. The gerund ends in -ing and functions as a noun.  Examples: Giving, Waiting, Talking, etc.

b) A participle is a verbal that functions as an adjective.  Two kinds of participles are Present and Past participles.  Examples include: sleeping in "sleeping dogs," injured in "injured player."

c) An infinitive is the basic form of the verb and always begins with the word: "to."  Examples include: to learn, to study, to dance.
