Here's why:
* Prepositions show the relationship between a noun or pronoun and another word in the sentence. They typically answer questions like "where?", "when?", or "how?"
* Example: "The book is on the table." ("On" shows the relationship between the book and the table.)
* Adverbs modify verbs, adjectives, or other adverbs. They tell us how, when, where, or to what extent something happens.
* Example: "The cat sat there." ("There" tells us where the cat sat.)
