The kanji 容容 is a 形声文字 (keisei moji), a phono-semantic compound. The phonetic component is 谷（tani - valley), which gives a clue to the pronunciation. The semantic component is 宀, which indicates a roof or a house or a container. The combination of these parts gives the meaning of the kanji, the act of "containing" something within a space. This character evolved over time, taking on various nuances of meaning related to its core concept of containment and the appearance of things.
