Ready to test your linguistic reflexes? Today we're playing "Guess the word." Here's how it works. We pass along a number of meanings associated with a word (and we will not begin with the obvious ones); your job is to figure out which word we are talking about. All set?

We begin by noting this verb can be both transitive (it takes an object) and intransitive (it doesn't). Ready? Our mystery word has two very old, now obsolete senses: it meant "to beat" or "belabor" something, and it meant "to make a loud sudden noise; to knock or bang loudly."

Here's a hint: our mystery word is of imitative origin. And now, back to the definitions. Our verb has two chiefly British applications, "to bluff or bully with big talk; scold" or "browbeat," and "to talk big; bluster; swagger; boast."

Finally, we'll throw in a few more common applications: "to cause [something] to rebound" or "cause [it] to be reflected" and "to strike and rebound." Paired with back, our word means "to recover from a blow or a defeat quickly or vigorously." Used about a check, the word means "to be returned by a bank as no good," applied to a person, it means "to expel or eject from a room, place, membership, or participation."

Recoiling at the idea that you're only just now figuring out the word is bounce? Don't feel bad . . . we didn't make it easy.
