困乏

困乏 refers to a state of physical or mental tiredness, often due to overwork, lack of sleep, or prolonged activity. It is more specific than general terms like 'tired' and implies a deeper level of exhaustion that may require rest or recovery.

The character 困 (kùn) originally meant 'to be trapped' or 'to be in difficulty,' and later came to mean 'fatigue' or 'tiredness.' 乏 (fá) means 'lack' or 'exhaustion.' Together, they form a compound that emphasizes a feeling of being drained or worn out.

困乏 is commonly used in everyday language to describe the result of long work hours, stress, or insufficient rest. It is often used in medical or health contexts, and it can also appear in literature or personal accounts of daily struggles.
