To show a singular or plural possessive?

Answer 1

An apostrophe (') is used to indicate possession for singular or plural nouns.

Singular nouns that do not end with -s, add an apostrophe -s ('s) to the end of the word:

apple-> apple's

boy-> boy's

child-> child's

Singular nouns that do end with -s have two accepted ways of forming the possessive:

Add an apostrophe (') after the existing s at the end of the word: boss'

Add an apostrophe s ('s) after the existing s at the end of the word: boss's

Plural nouns that do end with -s, add an apostrophe (') after the ending -s:

apples-> apples'

boys-> boys'

bosses-> bosses'

Plural nouns that do not end with -s form the possessive the same as singular nouns that do not end with -s, add an apostrophe -s ('s) to the end of the word:

children-> children's

people-> people's

mice-> mice's
