'temporarily-built' originates from the combination of 'temporary' and 'built', where 'temporary' comes from Latin 'temporarius', meaning 'lasting for a time', and 'built' is the past participle of 'build', from Old English 'byldan'.

'temporary' evolved from Latin 'temporarius' through Old French 'temporaire', and 'built' is derived from Old English 'byldan', eventually forming the modern English term 'temporarily-built'.

Initially, 'temporary' meant 'lasting for a time', and 'built' meant 'constructed'. Together, they convey the idea of something constructed for a short duration.
