Adjectival and adverbial phrases are types of prepositional phrases, which incorporate a preposition followed with the aid of an object, or noun, and any modifiers. An adjectival phrase is one that describes or modifies a noun, and an adverbial phrase is one that modifies a verb. An adjective prepositional phrase will come proper after the noun or pronoun that it modifies. If there are two adjective prepositional phrases together, one will follow the other. A prepositional phrase may be used as an adverb. They tell how (manner), when (time), the place (place), how much (degree), and why (cause).
