xiphias

xiphias (ZIFF ee us) noun
Swordfish.
This word has appeared before in spelling bees, and I like it because it's a word we can, with a little effort, work into everyday life--assuming you eat swordfish. And if you have children who don't like swordfish, the word xiphias gives you an opportunity to start with a clean slate and see if you can't trick them into trying it again. Good luck with that.
