Prepositional Phrase vs. Adverbial Phrase: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 21, 2024
A prepositional phrase provides additional information about a noun, while an adverbial phrase modifies a verb, adjective, or other adverb.

Key Differences

A prepositional phrase begins with a preposition and ends with a noun or pronoun, called the object of the preposition. It functions as an adjective or adverb, providing more detail about nouns or pronouns. An adverbial phrase, on the other hand, is a group of words that functions as an adverb, modifying a verb, an adjective, or another adverb to convey manner, place, time, frequency, condition, degree, or reason.

In terms of structure, prepositional phrases typically consist of a preposition followed by a noun or pronoun. For example, in the phrase "on the table," "on" is the preposition, and "table" is its object. Adverbial phrases may include an adverb along with other words that expand on the adverb's meaning, such as “very quickly” or “with great caution.”

Prepositional phrases often provide spatial or temporal context, like "under the bridge" or "during the meeting." These phrases can act as adjectives, modifying nouns, or as adverbs, modifying verbs. Conversely, adverbial phrases modify verbs to add detail about how, when, where, or to what extent an action occurs, as in “ran quickly” or “spoke softly.”

The function within a sentence also distinguishes these phrases. A prepositional phrase can act as a subject, object, or complement, while an adverbial phrase primarily modifies verbs and sometimes adjectives or other adverbs, answering questions like how, when, where, and why.

Usage in a sentence is another differentiator. A prepositional phrase can provide necessary information about the subject or object, like "The book on the shelf is mine." In contrast, an adverbial phrase often adds optional information to the verb, as in "He ran quickly," where "quickly" is an adverbial phrase enhancing the verb "ran."
