echo

echo: [14] Echo comes via Old French or Latin from Greek ēkhó, a word related to ēkhé ‘sound’. It may have originated as a personification of the concept ‘sound’, which developed eventually into the mythological mountain nymph Echo, who faded away for love of Narcissus until nothing but her voice was left. (The Greek verb derived from ēkhé, ēkhein, is the ultimate source of English catechism.)
