'indifferently-produced' originates from the combination of 'indifferent' and 'produce,' where 'indifferent' meant 'without interest or concern' and 'produce' meant 'to create or manufacture.'

'indifferent' changed from the Latin word 'indifferens' and 'produce' from the Latin word 'producere,' eventually forming the modern English term 'indifferently-produced.'

Initially, 'indifferent' meant 'not different or distinct,' but over time it evolved into its current meaning of 'without interest or concern.'
