汉字: 矮
Pinyin: ǎi (third tone)
Short or low (in height).
矮 is commonly used as an adjective to describe objects or people with a short stature or low height.
The character 矮 is often used in everyday language to describe physical traits, but in Chinese culture, it is less common to directly comment on someone's height to avoid offense.
他比我矮一点。
He is a bit shorter than me.
The radical 矢 (arrow) combined with other components gives the idea of a shorter or smaller stature.
