So for the December challenge, I really wanted to try to pick something that people of all ages could participate in.
Your mission, should you choose to accept it, is to pick one word that you don't know at the beginning of each week (aka: today). You need to learn the word, it's definition, etc., and use that word once a day in your normal conversations.
In case you're curious, the word that I chose this week is susurrant. It means whispering or murmuring.
Good luck! Have fun! Make up your own rules :)
