The punctuation to show possession is an apostrophe.
- Singular possessives are formed by adding an apostrophe s to the end of a noun.
- For plural nouns that end in -s, the possessive are formed by adding an apostrophe after the existing -s; for irregular plural nouns that don't end with -s, the possessive is formed by adding the apostrophe s, the same as a singular noun.
Example: Stephen's car was parked in the driveway. (the car belonging to Stephen)
