11. Possessive forms of Indefinite Pronouns


Indefinite pronouns do not have special forms to show possession. Therefore, it is necessary to use the apostrophe and the s ('s) to show the possessive forms of these pronouns. The plural of the indefinite pronoun other is others. In the case of this plural form, the apostrophe is placed after the s. See some examples below:

everybody's job somebody's hat one's family another's problems

anyone's opinion

someone's wife each one's duty others' affairs (plural)

When else is added to an indefinite pronoun, it is regarded as part of the pronoun. In this case, the apostrophe and s are added to else to form the possessive.

I came home with someone else's hat.
Someone else's book was put in my desk.
