About
The character "骱" is structurally formed from the radical "骨", denoting bone, combined with "介", which serves both phonetically and semantically to imply intermediacy or a connecting point, thus etymologically defining a joint where bones articulate. Its meaning has remained specifically anatomical, referring to skeletal articulations without notable semantic shift, and the compositional logic of "骨" for substance and "介" for linkage continues to reflect this focused sense directly.
