strong and pliable, resilient
韌 centers on a combination of strength and flexibility: something that is tough yet pliable, able to bend without breaking. The given meanings of 'strong and pliable' and 'resilient' both express this core idea of durable elasticity.
韌 combines 韋 (tanned leather, suggesting flexibility) with 刃 (blade, suggesting strength). The character likely expresses the idea of something that is both tough and pliable, like well-worked leather.
The left side 韋 represents soft, flexible leather, while the right side 刃 is a sharp, strong blade. Together they show something that is both strong and pliable: resilient like a leather-wrapped blade.
For ジン, imagine a resilient genie (ジン) emerging from a leather bottle, bending but never breaking. The genie's strength and flexibility match the kanji's meaning.
