Infinitive Phrases ∞

An infinitive is the form of a verb that includes the word to and acts as a noun, an adjective, or an adverb.

Some examples include:

Noun: To skip is difficult for some people.

Adjective: That pizzeria is an invitation to a memorable time.

Adverb: It is exciting to snow board on the leeward side of a mountain.


An infinitive phrase is an infinitive with modifiers or a complement. For example,

I find it entertaining to walk around the city.

Prepositional Phrases

Preposition: A word that relates a noun or pronoun to another word in the sentence. The noun or pronoun is the object of the preposition.

Prepositional Phrase: Includes preposition, it's object, and any words that modify the object. The entire phrase serves as an adjective or an adverb.

Example:

The mouse under the table shrieked.

The prepositional phrase is "under the table" because the preposition is under, which relates it to it's object or noun, "mouse."
