'misclassified' originates from the prefix 'mis-' meaning 'wrongly' and the verb 'classify' from Latin 'classificare', where 'classis' meant 'class' and 'facere' meant 'to make'.

'classificare' transformed into the English word 'classify', and with the addition of the prefix 'mis-', it became 'misclassify', eventually forming the past participle 'misclassified'.

Initially, it meant 'to make a class wrongly', and this meaning has largely remained the same in modern usage.
