Root Explanation

Rusted → The word is derived from "rust" (from Old English *rust*, meaning the reddish-brown coating formed on iron) and the suffix "-ed" (indicating a past participle or state). The term "rusted" describes the state of having developed rust, indicating deterioration due to oxidation.

Memory Tip
