How it's used
Beyond its medical sense of muscle atrophy, this word is frequently used in casual speech to describe a state of extreme lethargy or a lack of drive. It carries a strong negative connotation, often implying that someone has lost their vitality or 'spirit' due to laziness or poor health. When used to describe sexual impotence, it is considered quite blunt and potentially offensive, so it should be used with caution in social settings.

Common mistake
Learners often confuse this with 萎, which is used in terms like 萎縮 for shrinking or wilting. While they share similar meanings regarding weakening, 痿 is specifically associated with physical paralysis or loss of function, whereas 萎 is more commonly applied to plants or abstract concepts like morale.
