The kanji 速 is a 形声文字 (keisei moji), a character that combines a semantic component (meaning) and a phonetic component (sound). The left side is the radical 辶, the "shinpnyou" radical, representing "movement" or "to go." The right side is 束, which contributes the sound "soku" and originally meant "bundle" or "to bind." The combination suggests the swiftness of something bound together and moving quickly, thus representing "speed." The character's form evolved over time, with the lower part of 束 simplifying into its current appearance.
