'inaccurately-divided' originates from the combination of 'inaccurate' and 'divide', where 'inaccurate' means 'not accurate' and 'divide' means 'to separate into parts'.

The term 'inaccurately-divided' evolved from the need to describe divisions that lack precision, combining the prefix 'in-' (not) with 'accurate' and 'divide'.

Initially, it meant 'not accurately separated', and this meaning has remained consistent in modern usage.
