Apostrophes to Show
Possession
2 Use apostrophes to show possession.
If you could not use apostrophes to show possession, you would
have to rely on long, tedious constructions such as “I drove the car of
my father to the house of Ray to study for the test of tomorrow,”
instead of “I drove my father’s car to Ray’s house to study for
tomorrow’s test.”
Making Nouns Possessive
There are two rules for making nouns possessive.
Rule 1: Add an apostrophe and s (’s) to form the possessive of
singular nouns and of plurals that do not end in s.
