Origin

This character combines a grass radical at the top with the component 溥 below, which serves as a sound hint suggesting the pronunciation "haku". The grass component indicates the character relates to plants—specifically pampas grass, a thin, delicate grass. Over time, the meaning expanded from this slender grass plant to the general concept of anything thin or dilute, since thinness is a natural quality associated with grass blades and other vegetation. The visual connection between thin grass and thin liquids or weak tea helped the meaning broaden beyond just the plant itself.
