End

end, close, tip, powder, posterity

Mnemonic

At the end of the earth, one solitary tree clings to the cliff's edge. Beyond it—pure void. This lone tree is the last landmark, the furthest tip of all existence. Walk past that one tree and everything ends.
Additional thoughts
Visualize a dramatic cliff edge with a single tree silhouetted against an empty sky. The top stroke (One) caps the Tree like a horizon line—nothing beyond it. The longer top bar distinguishes End (末) from Not Yet (未).
Quick recall
One tree at the cliff's end—the last point before nothingness.

Details

The keyword for 末 is end. This kanji refers to the tip, extremity, or final stage of something, conveying the idea of reaching the furthest point or conclusion. It often implies the latter part of a period of time, such as the end of a week, month, or year. It can also suggest something trivial or insignificant, as things at the very tip or edge tend to be minor in nature.
