危

• Physical/Topographical: Lofty, steep, or high. In early contexts, this may be a neutral description of verticality (e.g., a cliff), but often implies the danger of falling or collapsing when human agents are involved.
• Abstract/Political: Precarious, endangered, or unstable; suggests a "tipping point" or the moment immediately preceding a fall.
• Technical (Astronomy): The 12th lunar mansion (associated with $\alpha$ Aquarii/Sadalmelik). In astrological or calendrical texts, this is a proper name for a celestial sector.

• Primarily functions as a stative verb or adjective.
• Can function as a noun ("the danger" or "precariousness"), particularly in later philosophical or political discourse describing an abstract condition.

• vs. 高 (gāo): While both denote height, 高 is generally neutral or positive (stature, nobility, elevation), whereas 危 denotes height that threatens to collapse or cause a fall.
• vs. 岌 (jí): Both imply instability, but 岌 specifically evokes the image of a steep, crumbling hill. The use of both in a passage typically emphasizes extreme fragility.
• vs. 險 (xiǎn) / 患 (huàn): While these also mean "danger," they often refer to external threats or hazardous terrain; 危 is more specifically tied to the instability of position and the risk of descent.

Graphical variants (e.g., U+21D32, U+21D41) exist but are paleographic in nature and do not alter the lexical range for standard translation.

When encountered in astrological or calendrical texts as a reference to the 12th lunar mansion, do not translate the glyph as "dangerous."
