'rarely-managed' originates from the combination of 'rarely,' meaning 'infrequently,' and 'managed,' the past participle of 'manage,' meaning 'to control or oversee.'

'Rarely' comes from Middle English 'rarelī,' and 'manage' comes from Italian 'maneggiare,' meaning 'to handle.'

Initially, 'rarely' meant 'seldom,' and 'manage' meant 'to handle or control,' which has remained consistent in modern usage.
