Some words, when you learn them, you wonder how you ever got along without them. And sometimes, there’s just no right word when you need one, so you have to make your own.

These 14 words fall into both categories for me. And I’ll bet, once you read them, you’ll end up adding at least one to your vocabulary. And hey, it doesn’t matter if other people don’t understand  — they’ll probably just assume you read more than they do.
