Make Waves With the History of Undulate

Undulate and inundate are word cousins that branch from unda, the Latin word for "wave." No surprise there. But would you have guessed that abound, surround, and redound are also unda offspring? The connection between unda and these words is easier to see when you learn that at some point in their early histories each of them essentially had the meaning of "to overflow"—a meaning that inundate still carries, along with its "overwhelm" sense.
