'standard-priced' originates from the combination of 'standard' and 'priced', where 'standard' meant 'a level of quality or attainment' and 'priced' refers to the cost of something.

'Standard' and 'priced' have been used in English since the late Middle Ages, with 'standard' coming from Old French 'estandart' and 'priced' from Old French 'pris'.

Initially, 'standard-priced' referred to items priced at a common rate, and this meaning has largely remained the same in modern usage.
