A state of being on the edge or margins of society, applied archaeologically in three interrelated ways. Physical liminality may be seen in terms of a place or activity being detached from the centre of things (e.g. a cemetery placed on the boundary of a territory) in a ‘liminal zone’. Social liminality may be seen in terms of subcultures who are distanced from those who see themselves as the mainstream (e.g. peripatetic workers who join a community for while but then move on). Cultural liminality refers to a stage in the progression through a ‘rite of passage’ such as birth, initiation, marriage, or death, which often follows a tripartite structure involving separation, liminality, and reincorporation.
