On March 4, we let our inner nerd out for National Grammar Day! The day was established in 2008 by Martha Brockenbrough, the founder of the Society for the Promotion of Good Grammar. The day’s motto is: “It’s not only a date, it’s an imperative: March forth on March 4 to speak well, write well, and help others do the same!” We take that imperative seriously, so this National Grammar Day, we are celebrating the idiosyncrasies of the English language by studying up on common grammar mistakes, proofreading our correspondence, and thanking our editors!
