The left side is 石, meaning "stone," and the right side, 其, is the phonetic component, indicating the sound and contributing to the meaning. In this case, the "stone" element refers to the 碁石 (go stones) used in the game, and the sound element provides the phonetic clue. The character was created to represent the game where stones are placed on a board.
