介词

A preposition is a connecting word that shows the relationship between a noun or pronoun and another word, usually the subject in a sentence. They are commonly used to give information about time or location.
Prepositions are usually placed after the verb and before the noun or pronoun they are associated with. The noun following the preposition is never the subject of a sentence.
In this lesson you'll learn some very common prepositions that are used for both place and time.
