'neglectfully-handled' originates from the combination of 'neglectfully' and 'handled', where 'neglectfully' is derived from 'neglect' meaning 'to fail to care for properly', and 'handled' is the past participle of 'handle', meaning 'to manage or deal with'.

'neglectfully' evolved from the Latin word 'neglectus', and 'handle' from the Old English 'handlian'.

Initially, 'neglectfully' meant 'without proper attention', and 'handle' meant 'to touch or manage'. Over time, 'neglectfully-handled' came to mean 'managed with neglect'.
