infirm

This term carries a heavy connotation of fragility and decline, often evoking a sense of pity or clinical observation. When describing physical health, it suggests a permanent or chronic state of weakness rather than a temporary illness, typically associated with the natural erosion of the body over time. In a psychological or moral sense, the word describes a lack of stability or firmness in one's convictions. It portrays a person who is easily swayed or unable to maintain a steady course of action, shifting the focus from physical muscle to mental fortitude.
