'provisionally-assigned' originates from the Latin word 'provisionem,' meaning 'a providing,' and the Old French word 'assigner,' meaning 'to appoint or designate.'

'provisionem' transformed into the Middle English word 'provisioun,' and 'assigner' became 'assign' in modern English.

Initially, 'provisionally' meant 'for the time being,' and 'assign' meant 'to appoint,' which has largely remained the same in modern usage.
