'culture-bound' originates from the combination of 'culture' and 'bound,' where 'culture' refers to the customs, arts, social institutions, and achievements of a particular nation, people, or other social group, and 'bound' means restricted or confined.

'Culture-bound' evolved from the concept of being restricted by cultural norms and practices, eventually becoming a term used in anthropology and sociology.

Initially, it meant 'restricted by cultural norms,' and this meaning has largely remained the same in modern usage.
