What is the difference between an adverb and a preposition?
assistant
The main difference between an adverb and a preposition is that an adverb modifies a verb or an adjective, while a preposition is used to show the relationship of one word to another. An adverb can be either a single word such as “quickly” or a phrase like “very quickly.” A preposition typically consists of two words, such as “in front of,” which shows the relationship between the object and the subject.
