'abnormally-altered' originates from the combination of 'abnormal' and 'altered', where 'abnormal' comes from Latin 'abnormis', meaning 'deviating from the rule', and 'altered' from Latin 'alterare', meaning 'to change'.

'abnormis' transformed into the English word 'abnormal', and 'alterare' became 'altered', eventually forming the modern English term 'abnormally-altered'.

Initially, 'abnormal' meant 'deviating from the rule', and 'altered' meant 'changed'. Together, they evolved to describe something changed in an unexpected way.
