Apostrophe Rules

Apostrophes are used to indicate the omission of letters in contractions and to form the possessive case of nouns and pronouns.

Contractions

Apostrophes are used to indicate the omission of letters in contractions. A contraction is a shortened form of two words. The apostrophe is placed where the letters are omitted.

  • don’t (do not)
  • can’t (cannot)
  • won’t (will not)
  • I’m (I am)
  • she’s (she is)
  • they’re (they are)

Possessive Case

Apostrophes are used to form the possessive case of nouns and pronouns. The possessive case indicates ownership or belonging.

  • The boy’s book
  • The girl’s doll
  • The dog’s bone
  • My friend’s car
  • Their house

Plural Forms

Apostrophes are not used to form the plural of nouns. The plural of a noun is formed by adding an -s or -es to the end of the word.

  • book (singular) – books (plural)
  • girl (singular) – girls (plural)
  • dog (singular) – dogs (plural)

Common Apostrophe Errors

Apostrophe errors are among the most common grammatical mistakes. These errors can make your writing look unprofessional and can even change the meaning of your sentences. Here are some of the most common apostrophe errors and how to avoid them:

One of the most common apostrophe errors is using an apostrophe to create a plural noun. For example, “The dog’s barked” should be “The dogs barked.” Another common error is using an apostrophe to create a possessive noun when the noun is already plural.

For example, “The children’s toys” should be “The children’s toys.”

Apostrophes in Contractions

Apostrophes are also used to create contractions. A contraction is a shortened form of two words. For example, “can’t” is a contraction of “cannot.” When creating a contraction, the apostrophe takes the place of the letters that are omitted. For example, “won’t” is a contraction of “will not.”

Apostrophes in Possessive Nouns

Apostrophes are used to create possessive nouns. A possessive noun shows that something belongs to someone or something else. To create a possessive noun, add an apostrophe and an “s” to the end of the noun. For example, “the dog’s bone” shows that the bone belongs to the dog.

Advanced Apostrophe Usage

Apostrophes are used in a variety of special cases, including plurals of compound nouns, dates, and numbers.

  • mothers-in-law
  • attorneys general
  • courts-martial

Dates and Numbers
