Prepositions

A preposition links nouns, pronouns and phrases to other words in a sentence. The word or phrase that the preposition introduces is called the object of the preposition.

A preposition usually indicates the temporal, spatial or logical relationship of its object to the rest of the sentence as in the following examples:

   * The book is on the table.
   * The book is beneath the table.
   * The book is leaning against the table.
   * The book is beside the table.
   * She held the book over the table.
   * She read the book during class.
