The kanji 宰 is a 形声文字 (keisei moji), a phono-semantic compound character. The left side is the radical 宀 (うかんむり - ukanmuri), representing a roof or building, and by extension, a place of authority or a dwelling. The right side is 辛 (辛 - karai), which originally depicted a tool used to punish or a sharp object. 辛has also been interpreted as suggesting an official or someone in charge. Together, 宀 and 辛 combine to suggest the idea of someone who is in charge, ruling, or managing from a position of authority, like within a building.
