淳

• Physical: Unadulterated, concentrated, rich, or mellow (originally applied to liquids).
• Moral/Human: Sincere, guileless, honest, or unsophisticated; describes a character that is "unmixed" or lacks artifice.

Primarily functions as an adjective. In certain contexts, it may operate as a descriptive noun referring to a state of simplicity or purity.

• vs. 純 (chún): While both mean "pure," 純 typically denotes absolute or abstract purity, whereas 淳 is more organic and grounded in temperament or substance.
• vs. 樸 (pǔ): In the pairing 淳樸, 樸 refers to the raw, "uncarved" state (the lack of artifice), while 淳 refers to the sincerity and mellow quality of the spirit within that state.

• Variants: Frequent interchangeability with 醇 (grain radical). When describing fermented liquor or the strength of a brew, 淳 often serves as a semantic variant for 醇; conversely, 醇 can be used to describe an unadulterated human nature.
• Readings: Fanqie: 常倫; Tang-period reading: zhuin.

When translating "purity," distinguish this glyph from 清 (qīng). While 清 suggests a crystalline or transparent purity, 淳 denotes a purity characterized by richness, density, or consistency.
