1. Introduction to Apostrophes
What is an Apostrophe?
An apostrophe (‘) is a punctuation mark used to show possession (ownership) or to form contractions, which shorten two words into one.
Functions of Apostrophes

- Possessives: Apostrophes indicate ownership or association.
2. Apostrophes in Contractions
Definition of Contractions
A contraction is a shortened form of one or more words, where the apostrophe takes the place of omitted letters.
Common Contractions and Their Rules
- “It’s” vs. “Its”: “It’s” is a contraction for “it is” or “it has.” “Its” is a possessive pronoun, meaning “belonging to it.”
- Example: It’s going to rain. / The cat licked its paw.
- “I’m” vs. “Im”: “I’m” is a contraction for “I am.”
- Example: I’m going to the store.
- “Can’t” vs. “Cannot”: “Can’t” is the contracted form of “cannot.”
- Example: She can’t come today.
Examples of Contractions in Sentences
- I’m happy to help. (I am)
- She didn’t like the movie. (did not)

3. Apostrophes in Possessives
Definition of Possessives
Possessives show ownership or association with something. Apostrophes are used to form possessive nouns.
Rules for Possessives (Singular & Plural)
- Singular Possessives: Add an apostrophe + “s” to the singular noun.
- Example: The teacher’s book (The book belonging to the teacher)
- Plural Possessives: For plural nouns ending in “s,” add only an apostrophe.
- Example: The teachers’ books (The books belonging to the teachers)
Special Cases: Irregular Possessives and Multiple Owners
- Irregular Possessives: Some nouns do not follow the regular rules for possessives, such as children (children’s), men (men’s), or women (women’s).
- Multiple Owners: If two people own something jointly, only the second person’s name gets the apostrophe.
- Example: John and Mary’s house (The house owned by both John and Mary)
- Separate Ownership: If two people own things separately, both get an apostrophe.
- Example: John’s and Mary’s cars (John owns one car, and Mary owns another)
