A preposition is a word used to link nouns, pronouns, or phrases to other words within a sentence. Prepositions are usually short words, and they are normally placed directly in front of nouns. In some cases, you’ll find prepositions in front of gerund verbs.
Types of Prepositions
There are three types of prepositions, including time prepositions, place prepositions, and direction prepositions.
Time prepositions are those such as before, after, during, and until; place prepositions are those indicating position, such as around, between, and against; and direction prepositions are those indicative of direction, such as across, up, and down. Each type of preposition is important.
