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 typically describes the relationship between two words or phrases. An adverb can also be used to describe time, place, manner, and other aspects of speech and writing. A preposition can also indicate direction, but it does so in terms of physical location rather than abstract concepts.
