Possessive Case

​

The possessive case of a noun or a pronoun shows ownership or possession.

​

EXAMPLES

Jorge’s calculator has a solar battery.

​

Pam’s aunt is a plumber.

​

​

​To form the possessive of most singular nouns,

add an apostrophe and an s.

​

EXAMPLES

Barbara’s house one boy’s uniform

a week’s salary that stereo’s speakers

​

​To form the possessive case of a plural noun ending in s, add

only the apostrophe.

​

EXAMPLES

cats’ owners cities’ problems

coaches’ records princesses’ duties

​

​The few plural nouns that do not end in s form the possessive case

by adding an apostrophe and an s.

​

EXAMPLES

geese’s migration children’s stories
