KanjiJLPT N1
Overcome

overcome, kindly, skillfully

Mnemonic

Your older brother hauls a massive cross up a brutal hill. Sweat pours, legs buckle—but he refuses to fall. With a roar, he overcomes the impossible climb, planting that cross at the peak as proof that sheer will can overcome any obstacle.
Additional thoughts
Picture the cross sitting on top of older brother—just like the kanji structure (十 over 兄). The image of him struggling uphill with a cross on his back makes the composition and meaning stick.
Quick recall
Older brother carries a cross uphill and overcomes the brutal climb.
