'hazardously-blended' originates from the words 'hazardous' and 'blend'. 'Hazardous' comes from the Old French word 'hasard', meaning 'game of chance', and 'blend' comes from the Old Norse word 'blanda', meaning 'to mix'.

'hazardous' changed from the Old French word 'hasard' and 'blend' from the Old Norse word 'blanda', eventually forming the modern English term 'hazardously-blended'.

Initially, 'hazardous' meant 'risky or dangerous', and 'blend' meant 'to mix'. Together, they evolved to describe a risky mixture.
