Meaning and history
Echo is a name derived from the Greek word ἠχώ (echo), meaning “echo” or “reflected sound,” and related to ἠχή (eche), meaning “sound.” In Greek mythology, Echo was a nymph whom Hera cursed with a speech impediment so she could only repeat the words of others; after falling in love with Narcissus and being rejected, she wasted away until only her voice remained.
Echo moved from #845 to #846 for girls between 1983 and 1984. That year also produced its highest recorded birth count, at 182.
