Here's a breakdown:
* Preposition: A word that shows the relationship between a noun or pronoun and another word in the sentence. Examples: on, in, under, over, to, from, with, by, for, etc.
* Object of the preposition: The noun or pronoun that follows the preposition. It answers the question "what?" or "whom?" after the preposition.
Example:
* The cat sat on the mat.
* "on" is the preposition.
* "mat" is the object of the preposition.
Why it's important: Understanding the object of a preposition helps us understand how phrases are structured and how words connect within a sentence.
