深

• Physical/Spatial: Vertical depth (e.g., water, pits) and immersive remoteness (e.g., being deep within a forest, mountain range, or territory).
• Temporal: Lateness (e.g., the "dead of night").
• Abstract/Intellectual: Profundity or unfathomability; subjects that are arcane, subtle, or resist easy penetration.
• Qualitative: Intensity of color or flavor (dark or strong).

• Adverbial Intensifier: Functions as a modifier meaning "very," "extremely," or "deeply." In ambiguous syntax where the glyph precedes another descriptive term, it may be treated as a modifier of degree.

• Spatial: Distinguished from 遠 (linear distance) by its focus on immersive or interior distance.
• Qualitative: Distinguished from 稠 or 濃 (density or thickness).

// Reading: Tang-period reading //shim.

• Variants: Semantic variant U+23E27 is an orthographic detail with no impact on meaning.

The glyph's logic is rooted in verticality and descent, based on the phonetic 罙, which originally suggested a pit.
