The kanji 室 室 is a phono-semantic compound (形声文字, keisei moji). The character is composed of the radical 宀 (うかんむり, ukanmuri), which represents a roof or shelter, and the phonetic component 至 (し, shi), which gives a rough indication of the sound and originally meant "to arrive" or "to reach." Together, the components suggest a sheltered space that one reaches or enters, thus creating the meaning of "room" or "chamber." The development of this character reflects the importance of enclosed spaces in the development of human dwellings and activities.
