'co-managed' originates from the prefix 'co-' meaning 'together' and the verb 'manage', which comes from the Latin word 'manus', meaning 'hand'.

'manage' evolved from the Italian word 'maneggiare', which means 'to handle', and eventually became the modern English word 'manage'.

Initially, 'manage' meant 'to handle or control', and this meaning has largely remained the same in modern usage.
