Definition of Preposition (with Examples)

Prepositions are usually short words (e.g., on, in, at, about, for). Prepositions are placed before a noun to show that noun's relationship to something else in the sentence. For example:
  • The mouse is on the table.
  • (The preposition on shows the relationship between table and mouse.)
  • It is a knife for butter.
  • (The preposition for shows the relationship between butter and knife.)
The noun governed by a preposition (which nearly always follows the preposition) is known as the object of the preposition. For example:

  • It is a tray for appliances.
  • (In this example, appliances is the object of the preposition for. The preposition shows the relationship between applications and a tray.)
  • The harrier hovered over the field.
  • (In this example, the field is the object of the preposition over. The preposition shows the relationship between the field and the Harrier.)

USE WHOM AFTER A PREPOSITION

The object of a preposition is always in the objective case. Therefore, who never follows a preposition. You must use whom after a preposition.
  • You're pregnant by who?

AVOID ENDING A SENTENCE WITH A PREPOSITION

The word preposition means positioned before. A preposition is positioned before a noun to show that noun's relationship with another noun in the sentence. As prepositions are designed to sit before nouns, lots of people do not like it when nothing follows a preposition. For this reason, many people do not like it when a preposition ends a sentence.

Nowadays, it is a little outdated to state that a sentence cannot end in a preposition. However, as lots of your readers might not like it, it is best to avoid ending a sentence in a preposition.
  • Which brush did you paint with?
  • (This is not wrong, but some of your readers might not like it.)
  • With which brush did you paint?
  • (If this sounds too unnatural for you, use the version above or reword your sentence; e.g., Which brush did you use for painting?)
