毛máo

毛 (máo, "hair, fur, feather") appears in Simplified Chinese exactly as it has for centuries — a pictograph of a hand with bristles extending from it, capturing the essence of something coarse and protruding. As a radical, it lends its meaning to characters like 毯 (blanket), 笔 (brush), and 毫 (fine hair), showing how this simple image continues to shape the language.
