Explanation:

A preposition is a word used to connect things, pronouns, or expressions to different words inside a sentence. They act to associate the individuals, articles, time and areas of a sentence. Relational words are generally short words, and they are regularly set straightforwardly before things.

A preposition is a word or set of words that shows area (in, close, next to, on) or some other connection between a thing or pronoun and different pieces of the sentence (about, after, furthermore, rather than, as per).
