The kanji 額額 is a phono-semantic compound (形声文字). It is composed of two parts: the radical 頁 (page, head) on the left side, which acts as the semantic component indicating the meaning related to the head, and the phonetic component 各 (kaku), which indicates the pronunciation. The character was originally a picture of a human head with emphasis on the forehead area. Over time, the form evolved to its present shape, retaining the meaning of forehead, and also extended to encompass related meanings like amount or sum.
