IPA: /aɪˈkɒnəˌklæzəm/
KK: /aɪˈkɒnəˌklæzəm/
The beliefs or practices that oppose or reject established traditions, especially in religion or art.
Iconoclasm has played a significant role in shaping modern art movements.
Iconoclasm is formed from "icon" (from Greek "eikon", meaning image or likeness) and "klasma" (from Greek "klasmos", meaning breaking). The term refers to the breaking of images, particularly in a religious context, where it denotes the rejection or destruction of religious images and icons.
Think of 'images' ('icon') being 'broken' ('klasma') — that's why iconoclasm means the destruction of images.
