Learn English – Which case of pronouns should be used with prepositions

There are many kind of pronouns like personal pronoun, demonstrative pronoun, relative pronoun etc. Pronouns regardless of their classification can occur after preposition. The thing that needs to take care of is the case of a pronoun that comes after a preposition.

Notes from Fowler's Modern English Usage -

After a preposition the objective (accusative) form of a pronoun, where it differs from the subjective (nominative) form, must always be used.

For example -

i) Believe in him.

ii) Between us.

iii) For them.

This is especially important when two pronouns are linked by and or or. For example -

Between you and me (not I)

A gift from my brother and me (not I)

asked if there was any chance of him (not he) and Gina reconciling.

Some more examples -

Who is a relative or interrogative pronoun. Who is the subjective form, whose is the possessive form, and whom is the objective form. Now if I want to use that pronoun after a preposition, the objective form whom should be used according to the rule stated by Fowler.

To whom does it matter? (not who or whose)

Everybody is a indefinite pronoun. There is no difference between subjective form and objective form. In both form it's everybody, but the possessive form is everybody's

It's clear to everybody.

The demonstrative pronoun those has no difference in subjective form and objective form.

It concerns to those who failed to obtain the minimum qualifying marks.

Hope this helps....
