Origin

This character combines the wood radical on the left, which marks it as something made of wood, with the component 曹 on the right, which serves as a sound hint suggesting the pronunciation. The right side doesn't tell you what a vat is — it just hints at how to say the character. Together, the wood radical and sound hint create a character for large wooden containers like vats and tubs that were essential for storage and washing in everyday life.
