About
The character 妹 is a phono-semantic compound, with the semantic female radical 女 on the left indicating its association with women or female relatives, and the phonetic component 未 on the right. The component 未 originally depicted a tree with new sprouts, carrying the sense of “not yet,” which conceptually aligns with the character’s primary meaning of a younger sister, one who is not yet fully grown. Its core sense of a younger female sibling or same-generation female cousin has remained consistent throughout its history, and the character retains the same structure in both traditional and modern forms.
