Etymology: "Echoism" is a modern coinage built from "echo" and the suffix "-ism," and the older piece of it reaches back to Greek mythology. In Greek myth, Echo was a nymph who could only repeat the last words spoken to her, a punishment that left her unable to speak her own mind. The Greek word "ēkhḗ," meaning sound or echo, gave rise to the name, which passed through Latin "ēchō" and Middle English "ecche" before becoming the English noun "echo." The "-ism" ending comes from Greek "-ismos" through Latin, and it has long been used to name doctrines, conditions, and behaviours. Adding it to "echo" produced a term for the habit of unconsciously copying another person's speech or gestures, a mirror of the nymph's fate in a psychological key.
