'ransack' originates from Old Norse, specifically the word 'rannsaka,' where 'rann' meant 'house' and 'saka' meant 'to seek.'

'rannsaka' transformed into the Middle English word 'ransaken,' and eventually became the modern English word 'ransack'.

Initially, it meant 'to search a house,' but over time it evolved into its current meaning of 'to search thoroughly, often causing disorder or damage.'
