'privately-managed' originates from the combination of 'private' and 'manage,' where 'private' comes from Latin 'privatus,' meaning 'individual' or 'personal,' and 'manage' comes from Italian 'maneggiare,' meaning 'to handle.'

'privatus' transformed into the Old French word 'privé,' and 'maneggiare' became the Middle English 'managen,' eventually forming the modern English term 'privately-managed.'

Initially, 'private' meant 'individual' or 'personal,' and 'manage' meant 'to handle or control.' The combined term now refers to operations controlled by private entities.
