Etymology

Bamboo-like ⺮ tendons in the chest 

About

The character "筋" etymologically derives from its structural composition, integrating the bamboo radical "竹" above the component "肋", which itself consists of "月" indicating flesh and "力" signifying force, thereby conceptually alluding to the fibrous and resilient tissues responsible for bodily strength. Its original meaning was specifically anchored to tendons and sinews, the physical connectors enabling movement and leverage within the body. Over time, this semantic field expanded to include adjacent anatomical structures such as muscles and visible veins, reflecting a broader physiological application. Subsequently, the term underwent a metaphorical extension, coming to denote the essential or strengthening elements within various systems, such as the crucial points in a narrative or the fundamental framework of an idea, illustrating a progression from a concrete anatomical term to an abstract descriptor of core components.
