衰

Qualitative decline—a wasting away or loss of vitality, integrity, or power. This includes physical senescence and decrepitude (the state of being "worn out"), the erosion of political power or systemic mandates, and the weakening of physical environmental forces.

1. Intransitive Verb: The process of declining.

2. Adjective/State: Describing a condition of being diminished or weakened.

3. Noun: The period of decline itself, or specifically, the long trailing garments worn by elders or those in mourning.

• vs. 弱 (ruò): While 弱 denotes fragility or an innate lack of strength, 衰 implies a comparative loss—a state of weakness following a previous state of strength.
• vs. 減 (jiǎn): 減 refers to quantitative subtraction (numerical decrease), whereas 衰 refers to qualitative decay (loss of vigor or efficacy).
• vs. 凋 (diāo): 凋 is specifically botanical withering; 衰 is systemic and applies to organic, political, or physical entities.

In passages concerning court attire, mourning rites, or dress codes, the glyph may function as a concrete noun referring to ritual garments rather than an abstract decline. Avoid over-modernizing the term into economic or psychological categories (e.g., "recession" or "depression"); in ancient contexts, the decline is typically organic, physical, or political.
