"Undulate" and "inundate" are word cousins, sharing "unda," the Latin word for "wave," as their common ancestor. 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.
