'formally-produced' originates from the combination of 'formal' and 'produce,' where 'formal' means 'following established conventions' and 'produce' means 'to create or manufacture.'

'Formally' and 'produced' have been used separately in English since the Middle Ages, but their combination into 'formally-produced' is a modern construct to describe items made with adherence to formal standards.

Initially, 'formal' and 'produce' were used separately, but their combination now specifically refers to items made with formal standards.
