'client-activated' is a compound word formed from 'client' and 'activated'. 'Client' originates from Latin 'cliens', meaning 'follower', and 'activated' comes from Latin 'activare', meaning 'to make active'.

'Client' evolved from the Latin 'cliens' through Old French 'client', while 'activated' evolved from Latin 'activare' through Middle English 'activate'.

Initially, 'client' referred to a follower or dependent, while 'activated' meant to make active. Together, they now refer to processes initiated by the client.
