Hi! I’m Kathy Ide. In addition to being a published author, I’m a full-time professional freelance editor. For CAN, I’m blogging about tips for writers based on the manuscripts I edit.
Using an Apostrophe in Plural Words
Do not use an apostrophe for most plurals. Examples:
dos and don’ts
no ifs, ands, or buts
yeses and nos
Molly got three As and two Cs.
Five Toms, four Dicks, and three Harrys
I had to go to two DMVs to get my license renewed.
Exception: To avoid confusion, pluralize single lowercase letters by adding apostrophe-s. Examples:
a’s and b’s
x’s and y’s
