聦

• Physiological: The faculty of hearing; the ability to receive sound.
• Cognitive (Adjectival): Astute, sharp, or quick of apprehension; specifically a perceptive intelligence capable of grasping meaning or subtext quickly.
• Perceptive (Verbal): To listen with understanding; to "catch" the meaning of something.

Functions as a noun referring to the sense of hearing, or as an attribute/predicate describing a person's nature.

Unlike 智 (wisdom/knowledge) or 明 (clarity/insight), this glyph emphasizes the intake of information—the "sharpness of the antenna."

A semantic variant of 聰 (U+8070). The use of 聦 may signal an older orthographic layer or a preference for the concrete sensory aspect of hearing before the term became fully abstracted into intelligence.

When translating, terms such as "perceptive," "acute," or "quick" often better preserve the sensory nuance than generic terms like "smart" or "clever."
