'corrosive' originates from Latin, specifically the word 'corrosivus', where 'cor-' meant 'together' and 'rodere' meant 'to gnaw'.

'corrosivus' transformed into the Old French word 'corrosif', and eventually became the modern English word 'corrosive'.

Initially, it meant 'to gnaw away', but over time it evolved into its current meaning of 'tending to cause corrosion'.
