About
The character "弦" derives from the concept of a bowstring, as seen in its structure combining the semantic component "弓" meaning bow with the phonetic element "玄". Originally referring specifically to the string of a bow, its meaning extended to encompass the strings of musical instruments, sharing the inherent property of a taut line. This semantic broadening continued into mathematical terminology, where "弦" came to denote a chord of a circle or the hypotenuse of a right triangle, reflecting an abstraction from physical strings to geometric lines.
