About
The character 膜 is structured with the radical 月, derived from 肉 and indicating flesh or bodily tissue, combined with the phonetic component 莫. Its etymology points to an original meaning centered on thin biological layers, specifically anatomical membranes. Over time, the semantic range of 膜 expanded to encompass any thin, pliable sheet or film, including artificial coatings and layers in technological contexts, reflecting a conceptual extension from natural tissues to man-made materials.
