The antonym for "un damaged" is "damaged." Damage refers to the negative impact on a person, thing, or situation, typically caused by an external force, such as an accident or natural disaster. Anything that is damaged is no longer in its original, good condition. Its value, usefulness, and appearance may have been compromised to some extent. Damaged goods are often unable to function as intended or desired. Alternatively, a restored or repaired item can also be a valid antonym for un damaged. Repaired items are often fixed and restored to their original state or even better.
