Here's why:
* Prepositional Phrase: It starts with a preposition ("in") and includes an object ("a hurry").
* Adverb: It modifies a verb, adjective, or another adverb, providing information about how, when, where, or to what extent something happens.
For example:
* She walked in a hurry. ("In a hurry" modifies the verb "walked" and tells us how she walked).
* He was in a hurry to catch the train. ("In a hurry" modifies the adjective "hurry" and tells us about the degree of his hurry).
