Answer:
A prepositional phrase: contains a preposition
Explanation:
A prepositional phrase is a group of words that function as a single unit and that consists of a preposition and the object of the preposition (like a noun or a pronoun), and that may also contain (not always) modifiers of the object. There are two types: adjective phrases (when they modify a noun) and adverb phrases (when they modify a verb, an adjective, or another adverb).
Look at the following examples of sentences with prepositional phrases (underlined):
The classes were all held in the morning.
In: preposition; the: modifier of the object; morning: object.
Type of phrase: adverbial because it modifies the verb "held."
Classes like these keep the students busy.
Like: Preposition; these: object.
Type of phrase: adjectival as it modifies the noun "Classes."
