Another suggestion is, that the first syllable is the same as the root of cad-o, to fall; l and d, everybody knows, are easily interchangeable: as Odysseus, Ulixes: [Greek: dakruon], lacrima, tear, &c. &c.

Let a lady alone, and she does everything more gracefully than a man; but let some cad undertake to teach her, she distrusts herself and imitates the snob.
