KanjiJLPT N4
Death

death, die

Mnemonic

A lightning strike slams into the metal spoon you're holding mid-bite. The electricity rockets through the utensil, up your arm, and straight into your heart — instant death. Never eat soup outdoors in a thunderstorm.
Additional thoughts
Picture the absurd image of someone casually eating soup outside as dark clouds roll in. The spoon acts as a tiny lightning rod. Metal + storm = fatal mistake. The silliness of the scene (soup in a storm) makes it stick.
Quick recall
A lightning strike hits your spoon mid-bite, delivering instant death.
