What does the title mean? No, Not the “American Automobile Association.” Actually, it stands for August Acronym Article, and it contains a few helpful lessons about when and how to use acronyms. The first of which is that you should introduce your acronym in parenthesis at the first mention of the longer term. So the ambiguity of “AAA” becomes “August Acronym Article (AAA).”
To make an acronym plural, add a lower case “s” to the end. There is no need to use an apostrophe. If one CPA meets another CPA for lunch, their table will have two CPAs. When making an acronym plural, be careful to not add an s to the end if one of the abbreviated terms is plural. For example the plural of Center of Disease Control and Prevention (CDC) is Centers for Disease Control and Prevention, not Center for Disease Control and Preventions, so the acronym is still CDC. In scientific documents, do not add s to units for measure. For example 10 Millimeters is written as 10mm, not 10mms. The next time you use acronyms in a document, consult the AAA, although it won’t be much help if your car gets a flat tire.
