About
The character 弧 is structured with the semantic radical 弓, meaning "bow", and the phonetic component 瓜, which historically indicated pronunciation. Originally, 弧 referred specifically to a wooden bow, but its meaning expanded over time to denote any arc or curve, such as in geometric contexts, transitioning from a concrete object to an abstract shape descriptor.
