P ast Infinitive versus Present Infinitive
 
Lesson 3-39
Prompt:In like manner to the present infinitive, the past infinitive of any verb is formed when the word "to" is combined with a helping verb and the past participle of the verb. The infinitive comes as a phrase as in: "To have lived a good life". Infinitives are usually used as nouns, but they may be used as adjectives or adverbs.
