Would you help me start a word of the day?

I’m inviting everyone to toss in a new word each day, I’m especially looking for new words you’ve never heard before. The rules are they need to be legitimate words, not words you just wish were real. I need to be able to find it on a legitimate dictionary website. Please don’t forget the definition!

To start us off, my first word is Defenestrate. It means to throw out the window. Let’s have fun. Thanks!
