English Grammar/Basic Parts of Speech/Prepositions
A preposition connects the relationship between a noun, pronoun and phrase to other parts of the sentence. Whatever object or phrase the preposition is introducing is called the object of the preposition.
Each bold word in the following sentences are examples of prepositions:
The box is on the desk. The box is under the desk. The box is leaning against the desk. The box is beside the desk. He held the box over the desk. He looked at the box during lunch.
In each sentence a preposition is used to locate the box in time or space. People use prepositions every day without even realizing it. Think of a preposition as a way to relate the object to the rest of the sentence.
