'hazardous' originates from Old French, specifically the word 'hasard,' where 'hasard' meant 'game of chance.' 'Divide' originates from Latin, specifically the word 'dividere,' where 'di-' meant 'apart' and 'videre' meant 'to separate.'

'hazardous' changed from the Old French word 'hasard' and eventually became the modern English word 'hazardous.' 'Divide' transformed from the Latin word 'dividere' and eventually became the modern English word 'divide.'

Initially, 'hazardous' meant 'related to a game of chance,' but over time it evolved into its current meaning of 'involving risk or danger.' 'Divide' has largely retained its original meaning of 'to separate.'
