What theme does the term 'decrepit' convey?

The term 'decrepit' conveys a sense of age and decay, which is evident in its definition. Describing something as decrepit often indicates that it is worn down, weakened, or in a state of disrepair due to the passage of time. This can apply to both physical objects, like old buildings or machinery, and to living beings who may exhibit signs of aging or deterioration. While other choices might touch on related concepts, none encapsulate the essence of 'decrepit' as effectively as age and decay, making this the most fitting interpretation of the term.
