'provisionally-constructed' originates from the combination of 'provisionally,' which comes from the Latin 'provisionem,' meaning 'a providing,' and 'constructed,' from the Latin 'constructus,' meaning 'to heap up or build.'

'provisionally' evolved from the Latin 'provisionem' through Old French 'provision,' while 'constructed' evolved from the Latin 'constructus' through Old French 'construire.'

Initially, 'provisionally' meant 'for the time being,' and 'constructed' meant 'built.' Together, they convey the idea of something built temporarily.
