殊

The core sense is distinction or divergence, moving from neutral difference toward qualitative exception:

1. Different / Distinct: Separate from another; divergent. In early contexts, this often denotes a neutral lack of identity.

2. Special / Unusual: The result of being set apart from the norm.

3. Exceptional / Extraordinary: A development where distinction implies a higher or different grade of quality.

The glyph typically functions in three roles:

• Predicate Adjective: Describing disparity between two entities ("A is different from B").
• Attributive Adjective: Modifying a noun to indicate it is unusual or special.
• Intensifier (Adverbial): When preceding another adjective, it often means "especially," "particularly," or "very" (e.g., 殊美). In these cases, the adverbial reading should be prioritized over "different."

Among terms for "difference":

• 異 (yì) often implies a difference in kind, strangeness, or oddity.
• 別 (bié) emphasizes the act of separation, partitioning, or the process of distinguishing.
• 殊 (shū) focuses on the qualitative result of distinction—the state of being singular or exceptional.

Avoid projecting modern connotations of "special" (meaning "better") onto very early texts. In archaic usage, 殊 often denotes simple divergence or separation without an inherent value judgment.
