牙( yá )
字形:
古代牙字正像上下颌骨之间长有牙齿的样子。"牙"字古代专指生长在上下扣合的颌骨之间的臼齿。今天,它们都被统一称作"牙"。
The evolution of Chinese characters: The character for 牙(teeth) in ancient times looked just like a set of teeth. It originally referred to upper and lower molar teeth. Today, yá is collectively referred to as all teeth in the mouth.
