One of my favorite words is portmanteau, and not because it sounds like one of those fake towns in a steamy soap opera. (Okay, not only for that reason.)
A portmanteau is created when two existing words are blended to create a new word. Bromance, frenemy, ginormous and sexcellent are fantabulous examples of portmanteaus.
I love the spirit of this—an invitation to root around in the language and, if you can’t find something that expresses what you’re trying to say, to go ahead and disassemble a couple of existing words, duct tape them together and craft your own, brand-new word on the spot. It’s so…McGyver.
