IPA: /ˌɛkəˈleɪliə/
KK: /ˌɛkoʊˈleɪliə/
The automatic and often involuntary repetition of words or phrases that someone has just heard, commonly seen in certain psychological conditions.
The child exhibited echolalia by repeating everything the teacher said during the lesson.
Echolalia → It is formed from "echo" (from Greek "ēchō", meaning sound or to resound) and "-lalia" (from Greek "lalia", meaning speech or talk). The word "echolalia" refers to the repetition of phrases or sounds, often as a form of communication.
Think of 'echo' as a sound that repeats and 'lalia' as speech — so echolalia means repeating speech like an echo.
