A preposition is a small word that shows a relationship between other words in a sentence. It often describes direction, location, time, or introduces an object.
Prepositions are typically followed by an object — a noun, noun phrase, or pronoun.
There is no rule in modern English that says a sentence cannot end with a preposition. This is a common myth from older grammar traditions. In fact, ending with a preposition can sound more natural and less formal.
