'abnormally-moved' originates from the combination of 'abnormal' and 'move', where 'abnormal' comes from Latin 'abnormis', meaning 'deviating from the rule', and 'move' from Latin 'movere', meaning 'to move'.

'abnormis' transformed into the English word 'abnormal', and 'movere' became 'move', eventually forming the compound 'abnormally-moved'.

Initially, 'abnormal' meant 'deviating from the rule', and 'move' meant 'to change position', evolving into the current meaning of 'moved in an unusual way'.
