The kanji 鯨 is a phono-semantic compound (形声文字, keisei moji). The left side, radical 魚 (うお, uo), means "fish" or "aquatic animal," indicating the general category. The right side, 京 (きょう, kyou), acts as a phonetic component, representing the sound "gei." Thus, the character visually and semantically combines the idea of a "fish" with a sound association, forming the word for "whale."
