KanjiJLPT N2
Tender

tender, weakness, gentleness, softness

Mnemonic

A halberd chops into a tree, but instead of splitting, the tree bends gracefully around the blade. Its wood is so tender and supple it absorbs every blow. The warrior drops his halberd, amazed — the tender, yielding tree defeated him without breaking.
Additional thoughts
Think of a willow tree flexing around a weapon — softness overcomes hardness, the core principle of judo (which uses this kanji). The halberd is rigid; the tree is flexible. Flexibility wins.
Quick recall
A halberd strikes a tree, but the tender, supple wood bends instead of breaking.
