6. Grammar and Mechanics - Apostrophes and Other Punctuation Punctuation marks such as apostrophes, parentheses, dashes, and quotes may not seem like the most important elements in your writing. These small details, however, can change the meaning of your message and, if used incorrectly, can confuse your reader. Familiarize yourself with all punctuation marks, and understand how to use them to enhance your writing. How would you make a singular coworker possessive?

The correct answer is letter "A": Coworker's paycheck.

Explanation:

One of the uses of apostrophes (') in grammar is to show possession. In such a case, the apostrophe and an "s" are added to nouns at their end ('s). If the noun is plural ending with an "s" only the apostrophe (') is added. The other use of apostrophes is to show that words have been contracted (e.g. I am = I'm).

Thus, the noun "coworker" in its singular form shows possession in the phrase:

Coworker's paycheck.
