'dilapidation' originates from Latin, specifically the word 'dilapidare,' where 'di-' meant 'apart' and 'lapidare' meant 'to throw stones.'

'dilapidare' transformed into the Medieval Latin word 'dilapidationem,' and eventually became the modern English word 'dilapidation.'

Initially, it meant 'to throw stones apart,' but over time it evolved into its current meaning of 'falling into decay or disrepair.'
