IPA: /nɒn.kəˈrɒs.ɪv/
KK: /nɑnˈkɔrəsɪv/
A word used to describe a substance that does not cause damage or deterioration to materials, especially metals.
The noncorrosive coating protects the metal from rusting.
Noncorrosive → It is formed from "non-" (meaning not) and "corrosive" (from Latin "corrodere", meaning to gnaw or eat away). The word "noncorrosive" means not capable of causing corrosion or damage to materials.
Think of 'not' ('non-') causing something to 'gnaw away' ('corrosive') — that's why noncorrosive means it doesn't damage.
