Answer:
The correct answer is: Prepositional phrases don't include verbs.
Explanation:
Infinitive phrases can function as nouns, adjectives, or adverbs. An infinitive phrase begins with an infinitive (to+ simple form of the verb) and includes objects and modifiers.
For example:
<u>to kill a mockingbird</u>
A prepositional phrase is a group of words that consists of a preposition and a noun or a preposition and a pronoun. A prepositional phrase modifies a verb or a noun and it does not contain either a verb or a subject and it functions as a unified part of speech.
For example:
The shirt <u>with flowers</u> is mine.
The main difference between an infinitive and prepositional phase is the fact that <u>prepositional phrases don’t include verbs</u>. If the phrase follows a verb, then it is an infinitive phrase, as the prepositional phrases do not contain verbs.
