National Learn a Word Day
annually on October 16th
Today is a day to learn a word, which is the "smallest element that can be uttered in isolation with objective or practical meaning." Words can be in spoken or written form. It is unclear when or why this day started, but it probably exists because it is Noah Webster's birthday, and happens to be National Dictionary Day as well.
How to Observe
Celebrate the day by learning a word—or a few words! There are many apps such as Word of the day that you could use to help you learn words. You could buy some Word Smart books or find them online. If you are really up for a challenge, try learning some of the longest words in the English language!
