Origin & History of “hostage”
Despite its similarity, hostage is not related to any of the English words host. It comes via Old French hostage from *obsidāticum, a vulgar Latin derivative of late Latin obsidātus ‘condition of being held as a security for the fulfilment of an undertaking’. this is turn was based on Latin obses ‘hostage’, a compound noun formed from the prefix ob- ‘before’ and the base of sedēre ‘sit’ (English obsess (16th c.) is made up of virtually the same elements). The use of hostage for the ‘person held’ was established before English took it over.
