Origin

The character 脊 is built from the flesh radical (the left-side component meaning body or meat) combined with a right-side element. The right side appears to derive from an ancient picture of a backbone or spine running vertically upward through the body. Since the spine is what holds up the body and determines how tall someone stands, this visual foundation naturally led to the character meaning both spine and stature or height. Over time, the pictographic elements became more abstract, but the connection between the backbone imagery and the meanings of vertical support and physical height remained.
