Prepositional is a word that expresses a relationship between a noun/pronoun and another word in a sentence. Easier way to put it would be like saying you take a object or noun (ex: home) and also make up a location (ex: in), basically noun relation to a verb.
Example: <u>In my house</u>, you'll find my dog. House relates to where the dog is.
