I may participate in the annual A-Z challenge only twice due solely to the letter X. It's not writer-friendly.
Last year, I used "X-ray," because my mom had fractured her shoulder in February, and the X-ray of her broken joint was perfect. Thanks, mom.
This year....xylophone is all that came to mind. And, I just didn't feel the love. So, I formed an X out of mini marshmallows, then I googled X words. They're mostly unpronounceable. Like this one: Xylyl. Good luck. It has something to do with chemistry.
I did discover a word that was interesting: Xenial. It looks like someone just misspelled d-enial. It's pronounced Zeen-ee-ul. Why it's not spelled with a Z, I don't know. If would make life easier for everyone.
Xenial is my X word. It means hospitable. Isn't that nice? I don't think it gets much use, though. When I want to describe someone as hospitable, I say they're hospitable, not zenial...whoops, xenial.
This word is never gonna make it.
