Prepositions are short words, which are used to link noun, pronouns and phrases to other words in a sentence. The word or phrase that is introduced by a preposition is recognized as the object of the preposition. In other words, prepositions are the words that show relationships between other words in the sentence. A relationship can be a place, time, direction, amount or manner. For instance, John will be here at 6 o’clock. (Here, ‘at’ is a preposition that indicates the time.)
