“Everyday” is a perfectly good adjective, as in “I’m most comfortable in my everyday clothes.” The problem comes when people turn the adverbial phrase “every day” into a single word. It is incorrect to write “I take a shower everyday.” It should be “I take a shower every day.”
Today's entry originally ran on January 1, 2006—the first day of the first edition of the Common Errors in English Usage calendar. The print calendar was called the "Daily Boxed Calendar" because "Page-a-day" is trademarked. With the benefit of hindsight I see it should have been called the "Everyday Every Day Calendar."
This is the ten-year anniversary of the Common Errors in English Usage calendar. To celebrate, we are bringing back some of our favorite interesting, funny, but sometimes merely silly entries through the years before going on hiatus in 2016.
