About
The character 弟, which remains unchanged between traditional and simplified systems, originates from a pictographic representation of a sequence, depicting an object wrapped with cord or leather thongs around a vertical stand. This imagery of orderly binding gave rise to its core meaning of sequence or order, particularly among male siblings born from the same parents. Over time, its primary semantic focus narrowed specifically to denote a younger brother, embodying the concept of a later-born male within a family hierarchy. This familial sense was then extended metaphorically into broader social and philosophical contexts, giving rise to terms like 弟子 (disciple), where it conveys a sense of humility and junior standing within a teacher-student relationship, and informing its use in classical texts regarding fraternal duty and respect.
