'inefficiently-structured' originates from the combination of 'inefficiently' and 'structured'. 'Inefficiently' comes from 'inefficient', which is derived from Latin 'inefficientem', meaning 'not producing the desired effect'. 'Structured' comes from Latin 'structura', meaning 'a fitting together, building'.

'Inefficiently' evolved from the Latin 'inefficientem' through Old French 'inefficiente', and 'structured' evolved from Latin 'structura' through Old French 'structure'.

Initially, 'inefficiently' meant 'not producing the desired effect', and 'structured' meant 'a fitting together'. Over time, 'inefficiently-structured' evolved to mean 'organized in a way that is not effective'.
