Prepositions :

A preposition is a word placed before a substantive to show its relation to some other word in the sentence.

The substantive which follows a preposition is called its object.

A preposition is said to govern its object.


The surface of the water glistened.

OF makes it clear that surface belongs with water.


Philip is on the river.

ON shows Philip’s position with respect to the river.

IN or NEAR or BEYOND would have indicated a different relation. Water is the object of the preposition OF and river is the object of the preposition ON.

A preposition often has more than one object.

Over hill and dale he ran.

He was filled with shame and despair.
