Fight

fight, war

Mnemonic

Two warriors enter through the gate into an arena where beans are scattered across the floor — each bean worth a king's ransom by ancient measurement. They fight savagely, slipping on beans, slamming each other into the gate, battling over every last precious bean.
Additional thoughts
Picture the gate as a grand arena entrance, beans as precious spoils littering the ground, and measurement as the ancient standard that made each bean priceless. The image of warriors slipping on beans mid-combat locks the radicals together.
Quick recall
Warriors burst through the gate, scramble over beans valued by rare measurement, and fight savagely for every last one.
