速 means speed.
As an HSK Level 3 character, 速 is an intermediate-level character.
速 is a compound character with 辶 (walking) as the semantic radical, indicating movement, and 束 (bundle) as the phonetic component. The original meaning was 'to hurry' or 'to invite urgently,' later generalized to 'speed.'
💡 Memory Tip: Picture someone walking (辶) so fast they leave a bundle (束) trailing behind them in the wind.

速 is composed of the radical 辶 (walking) on the left and 束 (to bind) on the right. The radical suggests movement, while 束 adds the idea of 'tight' or 'fast' — together they imply moving quickly, like being bound to speed. This structure directly supports the character's meaning of 'speed' or 'fast'.
