光

1. Luminosity and Radiance: Physical light (celestial or artificial) or brilliance. This extends metaphorically to signify glory, honor, or prestige.

2. Limitation: Only; merely.

3. Bareness or Smoothness: Polished, stripped bare, empty, or bald.

Functions as a noun and adjective when referring to luminosity, and as an adverb (limiter) when meaning "only" or "merely," acting similarly to 唯 or 僅.

Distinguished from 明: 光 generally refers to the emission of radiance or the physical phenomenon of light; 明 more frequently denotes clarity, transparency, or intellectual understanding.

The variant U+2CEA7 is a graphical variation appearing in early manuscripts and inscriptions; it carries no distinct semantic weight and is equivalent to 光.

When the context does not support illumination or prestige, prioritize the "only/merely" reading.
