Meaning & readings

younger brother, faithful service to elders

On’yomi テイ、ダイ、デ

Origin

This character likely started as a picture of a younger person or a sequence showing the order of siblings. The shape suggests a figure in a bowing or submissive posture, which fits the meaning of a younger brother—someone who traditionally shows respect and deference to an older sibling. Over time, the pictographic strokes became more stylized and abstract, but the core idea remained: the visual form came to represent the concept of a younger family member and the dutiful service that role involves. The connection between the physical posture shown in the character and the social relationship it describes is typical of how many early Chinese characters formed their meanings.
