The word 肩胛骨 is formed by combining three characters: 肩, meaning "shoulder"; 胛, meaning "blade" or specifically "scapula"; and 骨, meaning "bone". Together, they create a compound term where 肩 locates the body part, 胛 specifies the blade-like structure, and 骨 denotes its skeletal nature, resulting in the literal meaning "shoulder blade bone" for the anatomical scapula.
