Which term describes something that has been harmed, injured, or spoiled?

The term that best describes something that has been harmed, injured, or spoiled is "damaged." This word specifically conveys the idea of something that has suffered a loss in its integrity or quality, typically due to external forces or conditions. When an object or situation is described as damaged, it implies that its original state has been compromised to the point where it may not function as expected or has visible signs of impairment.

While the terms "defective," "impaired," and "flawed" also suggest a problem with the object or situation, they are not as broad or direct in their meaning. "Defective" usually refers to something that has a manufacturing problem that prevents it from functioning properly. "Impaired" implies a reduction in function or quality, often used in contexts such as health or ability rather than physical objects. "Flawed" indicates that there is a mark, blemish, or error, but it does not necessarily denote harm in the same comprehensive way "damaged" does.

In summary, "damaged" is the most accurate choice for describing something that has been harmed, injured, or spoiled, as it encompasses a variety of contexts where deterioration has occurred.
