What does rusted mean?
Rusted means affected by rust, especially when iron or steel has been corroded by exposure to moisture and oxygen. It is both an adjective and the past tense and past participle of the verb rust, so it can describe a corroded object or describe the process that caused the corrosion: the hinges rusted, or the lock rusted shut. In figurative informal use, rusted can suggest that a person, skill, or place has deteriorated through neglect or lack of use, though rusty is more usual in this sense. The word is common in both British and American English and is especially associated with old tools, gates, vehicles, machinery, and other iron objects. It carries a clear implication of damage and neglect rather than merely discoloration. Because rust is a visible sign of long-term exposure and chemical change, rusted often conveys the passage of time as well as deterioration.
