'permanently-bonded' originates from the combination of 'permanent' and 'bonded'. 'Permanent' comes from Latin 'permanens', meaning 'enduring', and 'bonded' is derived from 'bond', which comes from Old Norse 'band', meaning 'a tie or binding'.

'Permanent' evolved from the Latin 'permanens' through Old French 'permanent', while 'bonded' evolved from the Old Norse 'band' through Middle English 'bond'.

Initially, 'permanent' meant 'enduring', and 'bonded' meant 'tied'. Together, they evolved to describe a state of being inseparably joined.
