Origin

This character combines a cold or ice indicator on the left with a sound hint on the right. The left side shows two vertical strokes from the water radical, which in this position specifically marks things related to freezing and cold. The right component provides a pronunciation clue—it sounds like "tou," which matches the on'yomi reading. Together, the character visually signals "something cold" while the right part guides you toward the correct pronunciation, creating a phono-semantic compound that means frozen or congealed.
