Advanced Details: Should I write FAQs or FAQ’s?

To form the plural of abbreviations, you generally just add an “s” to the end, without using an apostrophe. For example, “CV” becomes "CVs","DVD" becomes "DVDs" and FAQ becomes “FAQs.” If the abbreviation includes periods, add the “s” before the period. For example, “Ed.” becomes “Eds.”

Here's a more detailed breakdown:

• No periods: Add an “s” to the end of the abbreviation. 
• With periods: Add an “s” immediately before the period. 
• Examples:
• “PhD” becomes “PhDs”
• “M.D.” becomes “M.Ds.”
• “p. 1–2” becomes “pp. 1–2”
