'indifferently-collected' originates from the combination of 'indifferent' and 'collect,' where 'indifferent' meant 'without interest or concern' and 'collect' meant 'to gather together.'

'Indifferent' changed from the Latin word 'indifferens,' and 'collect' from the Latin word 'colligere,' eventually forming the modern English term 'indifferently-collected.'

Initially, 'indifferent' meant 'not making a difference,' and 'collect' meant 'to gather,' evolving into the current meaning of 'gathered without care.'
