4. Components

Radical 氵 · Water Radical (water, liquid, or moisture)

Semantic Clue (形旁): 氵 (Indicates that the substance is related to water or fluid.)

Phonetic Clue (声旁): 气 (original sound: qì)

Water (氵) plus vapor/air (气) equals steam (汽): moisture turning into hot gas.

  • 氵 water semantic clue
  • 气 gas/air phonetic clue
5. History
Liushu category: Phono-semantic (形声)

Origin: Combined from the water sign (氵) to show liquidity and the ancient character for air or vapor (气) to indicate steam and rising gases.

Semantic Evolution: Originally denoting rising steam from heated water, it expanded to mean vapor, gas, and modern industrial terms like automobiles (汽车 - steam/gas vehicles).

  • The right component '气' originally depicted curling wisps of air or clouds.
