Prepositions are words that show the relationship between a noun or pronoun and another word in the sentence. They usually indicate location, direction, time, or manner. Some common prepositions include:
* on
* in
* at
* to
* from
* with
* by
* for
"Ever" is an adverb. It modifies a verb, adjective, or another adverb. It usually indicates time or frequency.
Example:
* Ever since I met you, my life has changed. (Here, "ever" modifies the adverb "since")
Note: While "ever" can be used in phrases that resemble prepositions, it's not functioning as a preposition itself. For example, "ever since" or "ever after" are adverbial phrases.
