'temporarily-assigned' originates from the combination of 'temporary' and 'assign,' where 'temporary' comes from Latin 'temporarius,' meaning 'of time,' and 'assign' comes from Latin 'assignare,' meaning 'to mark out.'

'temporarily-assigned' evolved from the combination of 'temporary' and 'assign,' which were used separately in Middle English and eventually combined in modern English.

Initially, it meant 'assigned for a short duration,' and this meaning has largely remained the same in modern usage.
