Root Explanation
Corroded → It is formed from "cor-" (meaning together) and "rodere" (meaning to gnaw). The word describes the process of something being gnawed away or worn down over time, often by chemical action.
Memory Tip
Think of something being 'gnawed away' ('rodere') together with the prefix 'cor-' suggesting a process that happens over time. This helps you remember that 'corroded' means something that has been worn down or damaged.
