'inefficiently-altered' originates from the combination of 'inefficiently' and 'altered'. 'Inefficiently' comes from 'inefficient', which is derived from Latin 'inefficientem', meaning 'not producing the desired effect'. 'Altered' comes from Latin 'alterare', meaning 'to change'.

'inefficiently' changed from the Latin word 'inefficientem' and 'altered' from 'alterare', eventually becoming the modern English phrase 'inefficiently-altered'.

Initially, 'inefficiently' meant 'not producing the desired effect', and 'altered' meant 'to change'. Together, they evolved to describe something changed in a way that lacks efficiency.
