Several words and phrases in our language have emerged from the myths and legends of Ancient Greece, with the life stories of various mythological characters inspiring terms relating to them all these centuries later.
Of all the mythological tales to have ended up in our dictionaries, though, perhaps the saddest and most tragic is that of the otherwise fairly unassuming word "echo."
The Mythical Origins of Echo

In the stories of Ancient Greece, Echo was the name of a mountain nymph, or oread, associated with Mount Cithaeron in central Boeotia, around 30 miles north of modern-day Athens. Cithaeron is featured in a number of Greek myths, including the hunting of Actaeon (who was transformed into a stag and killed by his own hounds), and the legend of Oedipus (who was abandoned on the mountain’s slopes as an infant). But in the legend of Echo, it was here where Echo resided, and it was here that she fell afoul of Hera, the jealous and powerful wife of the king of the gods, Zeus.
According to the best-known version of Echo’s origin story, Zeus was cavorting with her fellow nymphs in the Cithaeron Mountains one day, when Hera—rightly suspicious of her husband’s fidelity—came down from Mount Olympus to see what he was up to. Seeing Hera approach them, Echo stepped in and began distracting her with endless chatter, giving the nymphs just enough time to flee the scene and escape Hera’s wrath.
When Hera discovered what Echo had done, she punished her by removing her ability to talk freely. Instead, she was cursed to only ever be able to speak after being spoken to—and even then, to only be able to mindlessly repeat the last words spoken to her. It is this legendary punishment that is at least partly responsible for giving us the word echo as we still use it today.
Echo and Narcissus: A Tragic Encounter

As if Echo’s tale was not already tragic enough, shortly after Hera’s curse had taken effect, a beautiful young man named Narcissus arrived on her mountainside hunting deer. Echo immediately fell in love with him, but, unable to talk until he had spoken to her, all she could do was stare silently from the shadows of the trees. Even when at long last Narcissus caught sight of someone watching him and called out to Echo, she could only parrot back what he said to her, and remained completely unable to explain how she felt.
Eventually, when their conversation understandably became absurd, Narcissus spurned Echo, leaving her to once again pine away in the shadows. But the gods had not failed to see Narcissus’ unfair treatment of her, and as a result he too fell victim to their vengeance.
Having once been told that he would live a long life so long as he never recognized himself, Narcissus caught sight of himself in a clear pool of water on Echo’s mountain and immediately became so besotted with what he saw that he never left the waterside again. Instead, he withered away by the pool until nothing more than the narcissus flower that now bears his name remained. Watching the entire process happen—and still unable to do anything to prevent it—was Echo, who likewise pined away with the grief of it all, leaving only her echoing voice behind her.
