'standardly-produced' originates from the combination of 'standard' and 'produce,' where 'standard' meant 'a level of quality or attainment' and 'produce' meant 'to create or manufacture.'

'standard' evolved from the Old French word 'estandard,' and 'produce' from the Latin word 'producere,' meaning 'to lead or bring forth.'

Initially, 'standard' referred to a flag or banner, but over time it evolved to mean a level of quality, and 'produce' retained its meaning of creation or manufacturing.
