One way to picture it: a sound hits a hard surface and comes back to you — the same sound arriving a second time, a little later and a little weaker. Everything else the word does is that returning-again shape, moved from sound to words to ideas to events.
From the word’s history
English echo comes, via Latin echo, from Ancient Greek ēkhṓ — related to ēkhḗ 'sound, noise'. The Greek word was also the name of the nymph Echo, who in myth could only repeat the last words others spoke: the name and the sound-word sit on the same root.
echo 經拉丁文 ēchō 來自古希臘文 ἠχώ (ēkhṓ)，與希臘文 ἠχή (ēkhḗ)「聲響」同源。希臘神話裡的山林女神 Ēkhṓ 也是這個字：她被罰只能重複別人剛說完的最後幾個字。所以這個字從一開始就同時帶著「聲音」和「只能重複別人的話」兩層，正好對上今天 echo 從回聲延伸到覆述、呼應的用法。
