'permanently-held' originates from the combination of 'permanent' and 'held', where 'permanent' comes from Latin 'permanens', meaning 'remaining to the end', and 'held' is the past participle of 'hold', from Old English 'healdan'.

'permanens' transformed into the Middle English word 'permanent', and 'healdan' became 'held' in modern English, eventually forming the compound adjective 'permanently-held'.

Initially, 'permanent' meant 'remaining to the end', and 'held' meant 'grasped or retained'. Together, they evolved to mean 'kept indefinitely'.
