'permanently-formed' originates from the combination of 'permanent' and 'formed', where 'permanent' comes from Latin 'permanens', meaning 'enduring', and 'formed' from Latin 'formare', meaning 'to shape'.

'Permanent' evolved from the Latin 'permanens' through Old French 'permanent', and 'formed' from Latin 'formare' through Old French 'former'.

Initially, 'permanent' meant 'enduring' and 'formed' meant 'to shape', and together they convey the idea of something shaped to last indefinitely.
