'bondage-advocating' originates from the English word 'bondage' combined with 'advocate,' where 'bondage' refers to a state of being bound and 'advocate' means to support or promote.

'Bondage' and 'advocate' were combined in modern English to form the adjective 'bondage-advocating.'

Initially, 'bondage' referred to physical restraint, but in this context, it evolved to include the promotion of such practices.
