速い
はやい · hayai · JLPT N5 · i-adj
fast
🐇 速 = road-walk radical 辶 + bundle 束: moving down the road in a tight bundle
Sound hook: hayai starts like hi-YAH, the shout before a quick strike. Shares its reading with 早い (early); 速い is the one for speed, and the 辶 movement radical marks it as about motion.
