About
The character "弧" is structurally formed by the semantic component "弓", indicating a bow, and the phonetic element "瓜", which originally guided its pronunciation. Initially, the term referred specifically to a wooden bow used in antiquity, directly aligning with its radical's meaning. Over time, its application expanded beyond archery to describe any object with a curved shape, ultimately becoming the standard linguistic choice for denoting an arc in geometric contexts. This semantic transition from a concrete implement to an abstract mathematical concept illustrates how the character's inherent composition supported its adaptive usage across different domains.
