Peripeteia

So my word of the day.

Per·i·pe·te·ia also per·i·pe·ti·a (pÄ•r’É™-pÉ™-tÄ“’É™, -tÄ«’É™)
n.

A sudden change of events or reversal of circumstances, especially in a literary work.

Fortunately, I’m writing a (fairly brief) paper at the minute I’ll even get to use it in (and publish here soon because there’s no trivial late-penalties for this one!) So I’m not going to explode from knowing a cool word but having no place to use it. Yay-ness!
