4.13-Infinitive Notes

•An infinitive is a verbal consisting of the word “to” plus a verb (in its simplest "stem" form) and functioning as a noun, adjective, or adverb.

•

• The infinitive phrase includes the infinitive and any objects, complements, or modifiers

An infinitive phrase that acts like a noun will take on the functions of a noun (sub., DO, IO, OP).

Adjective infinitive phrases will come directly after a noun and modify it by answering “which?” or “what kind?.”

Adverb infinitive phrases usually answer “why?” or “how?.”

Infinitive Tips:
1. Can you replace the infinitive phrase with the word it? Then it is a noun. 
2. Is there a noun in front of the infinitive phrase? AND Does the infinitive phrase answer "which one" or "what kind"? Then it is an adjective.
3. Does the infinitive phrase answer "why" or "how"? Then it is an adverb.
