Possessive Nouns
Most possessive nouns will have an apostrophe -- but where you put that apostrophe can be confusing. Here are a few general rules to follow:
If the noun is plural, add the apostrophe after the s. For example: the dogs' bones.
If the noun is singular and ends in s, you should also put the apostrophe after the s. For example: the dress' blue color.
On the other hand, if the noun is singular and doesn't end in an s, you'll add the apostrophe before the s.
For example:the lizard's tail.
