(CNN)No need to study this month to increase your vocabulary. Merriam-Webster added 840 new words to the dictionary — and chances are, you probably know many of them.
A bulk of the new entries are already widely used, but a few additions will horrify old-school grammarians.
“Rando,” “adorbs” and “fav” are now sanctioned words. Blended words such as “mocktail” or “hangry” (hungry + angry) have made it in their own right. But possibly the most outlandish is “TL;DR,” which is shorthand for “too long; didn’t read.”
