"Understanding the correct preposition usage can be explained by example.You can change the meaning of a sentence by substituting one word for another. The girls ran toward the mall.The girls ran around the mall.The girls ran into the mall.The girls ran past the mall.In these sentences the words toward, around, into,and past relate the word mall to the act of running, telling where the girls ran.
. A preposition is always followed by a noun or pronoun that is called the object of the preposition. The object of each preposition in the above example sentences is mall.
