RULE.
A verb in the infinitive mood, refers to some noun or pronoun, as its subject or actor.
ILLUSTRATION of the examples under Rule XXIII. "To do" refers to thou understood for its agent; "to be improved" refers to talent; "to learn," to she; "to go," to they; and "to do," refers to him.
NOTE 1. The infinitive mood absolute stands independent of the rest of the sentence; as, "To confess the truth, I was in fault."
2. The infinitive mood is sometimes governed by conjunctions or adverbs; as, "An object so high as to be invisible;" "He is wise enough to deceive;" "The army is about to march."
RULE XXIV.
The infinitive mood, or part of a sentence, is frequently put as the nominative case to a verb, or the object of an active-transitive verb; as, "To play is pleasant;" "Boys love to play;" "That warm climates shorten life, is reasonable to suppose;" "He does not consider how near he approaches to his end."
NOTE. To, the sign of the infinitive mood, is sometimes properly omitted; as, "I heard him say it;" instead of, "to say it."
RULE XXV.
The verbs which follow bid, dare, need, make, see, hear, feel, help, let, and their participles, are in the infinitive mood without the sign to prefixed; as, "He bids me come;" "I dare engage;" "Let me go;" "Help me do it;" i.e. to come, to go, to do it, &c. "He is hearing me recite."
