Word on a Whim: Part I

I have a certain affinity for fun words. Among my current favorites are curmudgeon, pernicious, tenterhooks and pandiculate. Thanks to my fellow logophiles who've introduced me to those prime picks. Having a great new word to familiarize yourself with can make you notice what was once overlooked and is always a great conversation starter. I've subscribed to Dictionary.com's Word-of-the-Day emails and gotten juicy bobbles like gallimaufry and exegesis, and the GREs have graciously introduced me to obsequious and vituperative. So, here's to filling your mind's tool box.
Somewhat ironically, I came across today's Word on a Whim reading a book on Applied Positive Psychology.

Ineluctable: (adj.)unavoidable, not able to be escaped.
