Prepositions are words that show the relationship between a noun or pronoun and another word in the sentence. They often indicate location, direction, or time.
Here are some examples of prepositions:
* on the table
* in the room
* to the store
* at 3 o'clock
Reflexive pronouns, on the other hand, refer back to the subject of the sentence. They indicate that the action of the verb is directed back at the subject. Here are some examples of reflexive pronouns:
* myself
* yourself
* himself
* herself
* itself
* ourselves
* yourselves
* themselves
For example, in the sentence "He hurt himself," "himself" refers back to "He" and indicates that the action of hurting is directed back at the subject.
