花

Phono-semantic compound:

艸 (초, “grass/plant radical”) – provides the meaning (indicating a plant);

化 (화, “to become, to change”) – provides the sound.

In Korea and Japan, it is used almost exclusively as the noun “flower.”

In Chinese, however, besides meaning “flower,” it is also frequently used as a verb meaning “to spend” or “to use” (for example: 花钱 “to spend money”).
