There are three non-finite clauses:
- Infinitive clause (also known as infinitive phrase)
- -ing participle clause and -ed participle clause (also known as present participial phrase and past participial phrase, respectively)
- Gerund clause (also known as gerund phrase)
Of the three non-finite clauses, infinitive clause and participle clause are called non-finite adjectival clause (or adjectival verb phrase) when they function as adjective. Note that gerund clause can never function as an adjective. Examples (non-finite adjectival clause has been underlined):
