KanjiJLPT N1
Withstand

-proof, enduring

Mnemonic

A massive steel curtain slams down in front of you. You take a measurement of the force pressing against it—off the charts! You brace your back against the curtain, every muscle burning, struggling to withstand the unbearable pressure. Each measurement climbs higher, yet you refuse to break.
Additional thoughts
Picture yourself pinned against a thick curtain wall, a gauge beside you showing rising force. Your body is the last barrier. Curtain + measurement = withstand.
Quick recall
Bracing against a crushing curtain as the measurement of pressure skyrockets, you withstand it all.
