The kanji 宣 is a 形声文字 (keisei moji), a phono-semantic compound character. It is composed of the radical 宀 (うかんむり), which represents a roof or a house, and 亘 (わたる), which is the phonetic component, suggesting the sound and also the meaning of "across" or "throughout." Thus, the character originally meant something like "to make known throughout the house/community," evolving to the current meaning of "to declare" or "to announce."
