Possessive case of a singular noun?

Answer 1

Singular possessives are formed by adding an apostrophe s (s) to the end of a noun; for example:

• mother's car
• the city's roads
• the bird's nest

There are two accepted forms for possessive singular nouns ending in s:

Add an apostrophe (') after the existing s at the end of the word; for example:

• "Put it on the boss' desk."

Add an apostrophe s ('s) after the existing s at the end of the word; for example:

• "Put it on the boss's desk."

If you are a student, I recommend that you use the form your teacher prefers. If you are not a student, then use the form that you like.

Answer 2

To show possession of a singular noun, add an apostrophe followed by "s" ('s) to the noun. For example: "the dog's tail."
