Here are useful rules for the apostrophe. Learn them well, and use them in your writing.
1. Use an apostrophe to form the possessive of singular and plural nouns.
Add an apostrophe and an s to form the possessive of a singular noun.
Joe + ’s = Joe’s car
day + ’s = day’s effort
flag + ’s = flag’s colors
glass + ’s = glass’s cost
Note: If a plural noun ends in s, just add an apostrophe.
cars + ’ = cars’ interiors
televisions + ’ = televisions’ locations
Note: If a plural noun does not end in s, add ’s to the word.
mice + ’s = mice’s home
women + ’s = women’s department
Note: If a name of two or more syllables ends in an eez sound, the possessive is formed
without an additional s.
the tales of Ulysses = Ulysses’ tales
the speeches of Orestes = Orestes’ speeches
2. To make the possessive of a compound word or the name of a co-owned business or
organization, add ’s to the last word of the name.
