'standardly-divided' originates from the combination of 'standardly' and 'divided', where 'standardly' is derived from 'standard', meaning 'a level of quality or attainment', and 'divided' from 'divide', meaning 'to separate into parts'.

'standardly' evolved from the noun 'standard', and 'divided' from the verb 'divide', both of which have been used in English since the Middle Ages.

Initially, 'standardly' meant 'in a standard manner', and 'divided' meant 'separated into parts', which have largely remained the same in modern usage.
