Many people have trouble using apostrophes correctly. Here
are some rules, tips and practice exercises.
THE APOSTROPHE
A. The apostrophe is used to show that letters have been
left out. These are called contractions.
Examples:
can't for cannot
didn't for did not
it's for it is or it has
won't for will not
B. The apostrophe is also used to show possession (or ownership)
in the following ways:
If the thing/person that owns something is singular, add
's
Examples:
The girl's books
(the books belonging to the girl)
Mary's lamb
(the lamb belonging to Mary)
The princess's robes
(the robes belonging to the princess)
If the thing/person that owns something is plural and already
ends with an "s", simply add an apostrophe.
Examples:
The girls' books
(the books belonging to the girls)
The princesses' crowns
(the crowns belonging to the princesses)
If the thing/person that owns something is plural but does
not end in an "s", add 's
Examples:
The women's club
(the club belonging to the women)
The men's shirts
(the shirts belonging to the men)
Note: Pronouns do not have an apostrophe to show ownership:
yours
hers
ours
theirs
its
Example: The
cat scratched its fleas.
AN APOSTROPHE OF POSSESSION TIP
A useful method of knowing where to put the apostrophe of
ownership is to follow these steps:
1. Ask: " Who is the owner?"
2. Put the apostrophe after the owner
3. Add "s" if it sounds correct.
This is especially useful when plural words do not end in
"s".
Examples:
The lions den
(one lion)
1. Who is the owner of the den?
The lion
2. Put the apostrophe after the owner.
The lion'
3. Add "s" if it sounds correct. (It does)
