瘠

Core senses involve wasting or a lack of vital substance:

• Biological: Emaciated or gaunt; describing a body consumed by illness, starvation, or extreme frailty.
• Terrestrial: Barren or infertile soil that lacks the nutrients necessary to sustain growth.

Primarily used as an adjective. In certain syntactic positions, it may function as a stative verb meaning "to become emaciated" or "to waste away."

• Biological: Contrast with 瘦 (general thinness/leanness) and 纖 (slender/delicate); 瘠 specifically suggests the wasting away of flesh.
• Terrestrial: Frequently paired as the opposite of 肥 (fat/fertile). It is distinguished from 枯 (withered/dried up) in that 枯 refers to a loss of moisture, whereas 瘠 refers to a fundamental lack of nourishment.

The presence of the sickness radical (疒) indicates that this term implies pathology, depletion, or deprivation rather than neutral thinness.
