Common mistake Incorrect possessive form after a number

Incorrect possessive form after a number

One common mistake in English grammar is the incorrect use of possessive forms after a number. When indicating possession after a number, it is important to use the correct form of the possessive - either adding an "s" or an apostrophe followed by an "s" ('s).

Did you mean s or s'?

When using the possessive form after a number, it's important to understand whether the noun that follows is singular or plural. The general rule is to add an apostrophe followed by an "s" ('s) to indicate possession for singular nouns, and only an apostrophe (') for plural nouns.

  • Correct: The cat's bowl is empty. (Singular possessive)
  • Correct: The cats' bowls are full. (Plural possessive)

However, when it comes to possessive forms after a number, things can get a bit trickier. In this case, it is common to see the incorrect use of the singular possessive form.

  • Incorrect: I have 2 cat's at home.
  • Correct: I have 2 cats at home.

In the incorrect example above, the 's after "cat" indicates possession, but since there are multiple cats, the correct form should be "cats" without the apostrophe. The apostrophe should only be used when indicating possession for singular nouns.
