'provisionally-approved' originates from the combination of 'provisionally' and 'approved'. 'Provisionally' comes from the Latin word 'provisionem', meaning 'a foreseeing, foresight', and 'approved' comes from the Latin word 'approbare', meaning 'to assent to as good'.

'Provisionally' evolved from the Latin 'provisionem' through Old French 'provision', and 'approved' evolved from Latin 'approbare' through Old French 'aprover'.

Initially, 'provisionally' meant 'temporarily' and 'approved' meant 'accepted as satisfactory'. The combined term 'provisionally-approved' retains these meanings, indicating a temporary acceptance.
