'intensely-produced' originates from the combination of 'intense' and 'produce,' where 'intense' means 'extreme in degree' and 'produce' means 'to create or manufacture.'

'intense' and 'produce' were combined in modern English to form the compound adjective 'intensely-produced.'

Initially, 'intense' meant 'extreme in degree,' and 'produce' meant 'to create or manufacture.' The combination retains the original meanings to describe something created with high intensity.
