About
The character "颥" (rú), which specifies the temples of the head, is the simplified form of the traditional character "顬". Its structure is phono-semantic, consisting of the semantic component "页" (a simplified form of "頁"), denoting head-related concepts, and the phonetic component "需", though the modern pronunciation of "rú" diverges from "xū". Etymologically, this construction follows the standard pattern where one element indicates meaning and another suggests sound. The character's meaning has remained narrowly focused on its anatomical reference since its adoption, primarily appearing in compound terms like "颞颥" to describe the temple region.
