'intentionally-backed' originates from the combination of 'intentionally' and 'backed'. 'Intentionally' comes from the Latin word 'intentio', meaning 'a stretching out', and 'backed' is derived from the Old English 'bæc', meaning 'support'.

'intentionally' evolved from the Latin 'intentio' through Old French 'intencion', while 'backed' evolved from Old English 'bæc'.

Initially, 'intentionally' meant 'with intention or purpose', and 'backed' meant 'supported'. The combined term 'intentionally-backed' retains these meanings, emphasizing deliberate support.
