Incest tabooとは 意味・読み方・使い方

Incest taboo is a term used by anthropologists to refer to a class of prohibitions, both formal and informal, stated and unstated, against incest, the practice of sexual relations between certain or close relatives, in human societies. There are various theories that seek to explain how and why an incest taboo originates. Some advocates maintain that some sort of incest taboo is universal, while others dispute its universality. Research on the incest taboo necessarily involves research into what different societies consider "incest" which, according to anthropology, varies strikingly from one society to another. The term may encompass, but is not identical to, the legal regulation of marriage by states.
