'intentionally-built' originates from the combination of 'intentionally' and 'built', where 'intentionally' comes from the Latin 'intentio', meaning 'a stretching out', and 'built' is derived from the Old English 'byldan', meaning 'to construct'.

'intentionally' evolved from the Latin 'intentio' through Old French 'intencion', while 'built' transformed from Old English 'byldan' to the modern English 'build'.

Initially, 'intentionally' meant 'a stretching out', but over time it evolved into its current meaning of 'done on purpose'. 'Built' has largely retained its original meaning of 'to construct'.
