Something corrosive is a chemical or substance strong enough to slowly eat away at or destroy metal, stone, or other materials, like a strong acid. Doctors and scientists use this word for dangerous chemicals that can burn skin, too. People also use 'corrosive' for things that aren't chemicals at all, like corrosive comments or corrosive doubt, meaning they slowly damage trust, confidence, or a relationship over time, even when the damage is hard to see at first.
