陰

• Physical and Spatial: Shade, shadows, and coolness; the north side of a building or mountain; interiors, undersides, or recessed areas. Associated with moisture, dampness, and low temperature.
• Hidden and Clandestine: That which is out of sight, private, or secret. Early usage is typically neutral ("hidden from view"), while later contexts may be pejorative (deceptive, sinister, or conspiratorial).
• Chthonic/Funerary: The underworld or the realm of the dead; functions as a locative noun for the "dark place" or "place beneath."
• Metaphysical: The counterpart to 陽. Characterized as receptive, descending, contracting, or still.

Primarily functions as a noun (the shade, the north side, the underworld) or an adjective (dark, hidden, secret). Rarely occurs as a verb, where it typically implies the act of shading or concealing.

Distinguish between its use as a technical cosmological term and its use as a general descriptor of cold or dark qualities.

• Variants: U+9634 (semantic/simplified variant).

// Readings: Fanqie 於金; Tang-period //qim.

Rooted in the radical 阜 (mound/hill), fundamentally denoting the shaded side of a landform—specifically the north side in a northern hemisphere context.

• Gender Bias: Avoid reflexively translating as "female." The glyph often refers to qualities (passivity, receptivity) that were categorized as feminine in ancient binaries but do not necessarily refer to women or femininity.
• Contextual Layering: Determine if the author is operating on a physical level (shade/north), a behavioral level (secret/hidden), or a cosmological level (Yin).
