Etymology

The word cord traces back to Latin chorda, borrowed from Greek khordē, originally meaning "gut string" (used for musical instruments or bows). The term evolved to denote any flexible, rope-like structure, retaining its core idea of "thin, twisted fibers." The anatomical and measurement senses emerged later by metaphorical extension.
