17· Phonetic Root: 干 (gān)
5. History
Liushu category: Phono-semantic (形声)
Origin: Originally created to denote sweat (liquid exuding from the body, combining water 氵 and dry 干 as a phonetic indicator). Over centuries, it was borrowed to phonetically transcribe the nomadic title 'khan'.
Semantic Evolution: Shifted from purely physiological fluid (sweat) to serving as a phonetic loan character for foreign sovereign titles like the Mongol or Turkic Khans.
The title 'Khan' became prominent during the Mongol Empire, making this character crucial in East Asian historical texts.
