KanjiJLPT N4
Ability

ability, talent, skill, capacity

Mnemonic

Inside a tent at the circus, a performer holds a spoon up to the moonlight streaming in, then bends another spoon with his mind alone. The crowd gasps at his ability—no one has ever seen telekinesis performed live!
Additional thoughts
Two spoons bookend the moon in the kanji's structure. Picture the big-top tent overhead, moonlight pouring through, and the supernatural talent of bending metal. The double-spoon imagery reinforces that there are two spoon radicals.
Quick recall
Under a tent, a spoon catches moonlight and a second spoon bends—sheer ability.
