noun
contagious magic
Anthropological term for magic based on the principle that things once in contact continue to act on each other. Often contrasted with 類感呪術 (imitative magic).
感染呪術では、かつて所有者が身に着けていた衣服を使って呪いをかけることがある。
In contagious magic, a curse may be cast using clothing once worn by the target.
類感呪術 (imitative magic) works on similarity, while 感染呪術 (contagious magic) works on prior contact.
Compound of 感染 (contagion) and 呪術 (magic/sorcery), likely a calque from English 'contagious magic' used in anthropology.
