Etymology

忍 combines 刃 (blade) and 心 (heart/mind), suggesting the idea of a heart enduring a blade—bearing pain or hardship with inner strength.

Meaning mnemonic

A blade 刃 pressing down on the heart 心: enduring pain without showing it. This image captures bearing, concealing, and even sneaking—keeping a brave face while the heart is under pressure.

Reading mnemonic

For ニン, imagine a ninja enduring hardship in silence: nin -> ニン, and the ninja conceals their presence like the heart under the blade.
