Apostrophes

Note: there exists a typo in Rule 2B.

In special cases, such as when forming a plural of a word that is not normally a noun, some writers add an apostrophe for clarity.

Example: Here are some do's and don't's.

In that sentence, the verb do is used as a plural noun, and the apostrophe was added because the writer felt that dos was confusing. Not all writers agree; some see no problem with dos and don'ts.
