'deliberately-managed' originates from the combination of 'deliberate' and 'manage'. 'Deliberate' comes from Latin 'deliberatus', meaning 'considered carefully', and 'manage' comes from Italian 'maneggiare', meaning 'to handle'.

'deliberate' evolved from Latin 'deliberatus' through Old French 'deliberer', and 'manage' evolved from Italian 'maneggiare' through Middle French 'maneger'.

Initially, 'deliberate' meant 'to weigh in the mind', and 'manage' meant 'to handle or control'. Over time, 'deliberately-managed' evolved to mean 'carefully controlled'.
