笨bèn

笨 (bèn) in Simplified Chinese (簡體) retains its traditional shape, pairing the bamboo radical 竹 with the phonetic 本 that originally indicated the plant's root. Historically the character described the soft pith of bamboo, a material that seemed empty or lacking strength, which later led to the figurative sense of being clumsy or stupid. It is commonly used in expressions like 笨蛋 (fool), 笨拙 (clumsy), and 笨头笨脑 (slow-witted).
