'expertly-managed' originates from the combination of 'expertly' and 'managed', where 'expertly' is derived from 'expert', meaning 'skilled', and 'managed' is the past participle of 'manage', meaning 'to control or direct'.

'expertly' evolved from the Latin word 'expertus', meaning 'tried, tested', and 'managed' from the Latin 'manus', meaning 'hand', through Old French 'managier'.

Initially, 'expertly-managed' meant 'controlled by skilled hands', and it has retained this meaning in modern usage.
