The possessive case is used to show that something belongs to someone. To form the possessive, add an apostrophe s ('s) to the end of a singular noun. For plural nouns that end in s, just add an apostrophe after the s. When something belongs to multiple people, add an apostrophe after the plural s. Exceptions are made for people's names to avoid ambiguity.

the apostrophe(') after the plural s. Do not write
a second s.

parents’s house is really big.
However, if the plural noun is irregular, write the
apostrophe (') before the s.
