A preposition is a word placed before a noun, pronoun or gerund. It denotes the relation of the person or thing with something else.

a) The food is on the table.
In this sentence,  on shows the relation between the nouns table and food.
ii) I am fond of chocolates.
In this sentence, of shows the relation between the words fond and chocolates.

As given in the examples above, a word such as a noun, pronoun or gerund following a preposition is said to be the object of the preposition. It is always in the objective case.

A preposition is always followed by a noun and never by a verb. If we want a verb to follow a preposition , we must use the -ing form of that particular verb, which should be a gerund (verb in a noun form).
e.g. I am very fond of riding. (The base verb ‘ride’ here takes the ‘ing’ form)
