About
煤 is a phono-semantic compound. The semantic radical 火 (fire) on the left indicates its connection to combustion and heat. The right side, 某, provides the character's pronunciation. Its original meaning was soot, the black residue from burning. This later shifted to mean coal, the combustible rock used as fuel. The change from a fire's byproduct to its fuel source shows a natural semantic evolution, with the fire radical anchoring the character's association with burning and thermal energy.
