About
The character "沫" is structurally composed of the water radical (氵or 水) combined with the component "末", which denotes the tip or end of something, and this combination etymologically suggests the idea of water broken into its finest, most dispersed state. Its core meaning has consistently centered on fine liquid particles, originally referring to froth, foam, or spray, as seen in terms for the foam on water ("泡沫") or spray from a waterfall. Over time, this concrete meaning extended to similar substances, such as the froth of saliva or the head on a beer, while also carrying a classical metaphorical nuance of something insubstantial or fleeting, echoing the "末" component's sense of a minor or terminal part. The traditional form is identical in structure to the simplified one, and its semantic range has remained focused on this concept of liquid particulate matter without major deviation.
