妹 is made of 女 (woman) and 未 (not yet), suggesting “a woman not yet grown” — a poetic and visual way to describe a younger sister.

It reflects not only age but often affection and connection within a family. The same component 未 appears in 未来 (future), adding a layer of youthful potential to the imagery.
