火山
huǒshān · HSK 7
volcano
🌋 火山 = fire (火) + mountain (山) = a fire-mountain, a volcano
Both characters are pronounced in order: huǒ (fire) then shān (mountain). The compound literally stacks the two everyday words into the name for a volcano.
火 — pictograph of flames rising
火 is a pictograph showing flames rising upward from a fire, with the central stroke as the main blaze and the side strokes as sparks. The ancient oracle bone form looked even more clearly like a burning flame. It still means 'fire' today and serves as a common radical in characters related to heat, burning, or cooking.
山 — pictograph of three mountain peaks
山 is one of the oldest pictographs in Chinese, originally drawn in oracle bone script as three pointed peaks rising from a baseline. The form was simplified over time into the modern three vertical strokes on a base. Its meaning has stayed remarkably stable: 'mountain' or 'hill'.
