Here's why:
* Prepositions show the relationship between a noun or pronoun and another word in the sentence. They usually indicate location, time, or direction. Some common prepositions are "on," "in," "at," "to," "from," "by," "with," etc.
* "Anything" is a pronoun, which means it takes the place of a noun. It can be used as the subject, object, or complement of a verb.
Example:
* Correct: I don't want anything to do with that. ("Anything" is the object of the verb "want")
* Incorrect: I went anything the store. (This is incorrect because "anything" cannot be used as a preposition)
