The kanji 嵩 is a 形声文字 (keisei moji), a phono-semantic compound character. It combines a phonetic component with a semantic component. The semantic component is 山 (yama), meaning "mountain," and the phonetic component is 㒱 (sū) which suggests the sound and perhaps the idea of elevation. The combination creates the meaning related to height or volume, thus the meaning "bulk" or "volume."
