Which best identifies the difference between prepositional phrases and infinitives?

Question 4 options:

Prepositional phrases never include nouns.

Infinitive phrases never include verbs.

Infinitive phrases never begin with to.

Prepositional phrases don't include verbs.

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:

to kill a mockingbird

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 with flowers is mine.

The main difference between an infinitive and prepositional phase is the fact that prepositional phrases don't include verbs. If the phrase follows a verb, then it is an infinitive phrase, as the prepositional phrases do not contain verbs.
