To determine the part of speech of "over," we need a sentence where it is used. For example, in the sentence "The cat walked over the table," "over" would be a preposition.
Here's why:
* Prepositions show the relationship between a noun or pronoun and another word in the sentence.
* In the example, "over" shows the relationship between "walked" and "table" (the cat walked on top of the table).
