Able to be corroded; capable of being worn away or destroyed by chemical action like rust or acid.
From 'corrode' + the suffix '-ible' (from Latin '-ibilis' meaning 'able to be'). Established in English by the 17th century for describing materials vulnerable to corrosion.
The most corrodible common metal is actually iron, which is why pure iron almost never exists in nature—it immediately transforms into iron oxide, making iron perhaps the most eager element to corrode in Earth's atmosphere!
