What 速 means
It expresses speed or quick movement. An ancestor appears in a bronze inscription from ancient China’s early Spring and Autumn period. The character combines meaning and sound clues—not a picture of speed.
How is 速 pronounced?
The language and word determine the reading. Mandarin uses sù. Japanese uses soku in compounds; 速い is hayai, and 速やか is sumiyaka. In Korean, this Chinese-derived character is read sok, as in 속도, “speed.”
