of non finite verbs.They are usually preceded by the particle to and can be used as the subject or object of a sentence.For example,to run or to eat.Participles Participles are formed by adding suffixes(-ing,-ed)to the verb stem.They can be used as adjectives or adverbs in a sentence.For example,running or eaten.Gerunds Gerunds are formed by adding-ing to the verb stem and are used as nouns in a sentence.They express actions or states that are complete in themselves.For example,swimming or reading.Types of Non finite Verbs Non finite verbs do not have a specific tense form.However,they can be used with tense particles such as has or have to express an action in the past or present.For example,has gone or have seen.Tense Non finite verbs can be active or passive voice.The active
