'client-managed' is a compound word formed from 'client' and 'managed'. 'Client' originates from Latin 'cliens', meaning 'follower' or 'dependent', and 'managed' comes from the Italian 'maneggiare', meaning 'to handle'.

'Client' evolved from the Latin 'cliens' through Old French 'client', while 'managed' evolved from the Italian 'maneggiare' through Middle English 'managen'.

Initially, 'client' referred to a follower or dependent, while 'managed' meant to handle or control. Together, 'client-managed' now refers to systems or services controlled by the client.
