remainder, leftover, balance
残 centers on what remains after something is taken away or used up: a leftover, a remainder, or a balance. It captures the idea of something persisting when the rest is gone.
残 combines 歹 (death, damage) with 戋, which likely contributes the sound and the idea of smallness or reduction. Together they suggest something diminished or left over after loss.
The left side 歹 suggests death or damage, and the right side 戋 looks like two spears. Imagine a battle where most warriors are gone, and only a few damaged remnants remain: that is the leftover, the remainder.
For ザン, picture a Zen monk sweeping away everything, but a small pile of dust remains: Zen -> ザン, and that leftover dust is the remainder.
