KanjiJLPT N2
Root

root, radical, head (pimple)

Mnemonic

A tree in the middle of the pitch trips a footballer during a match. He slams into the dirt, claws at the soil, and rips up a massive root—thick, ancient, stubborn. He holds the root overhead like a trophy, proof of what lurked beneath the surface all along.
Additional thoughts
Visualize the footballer face-down in the mud, yanking out a gnarly root from under the tree. The root is the hidden foundation that tripped him—impossible to ignore once exposed. The trophy pose makes it stick.
Quick recall
A footballer trips over a tree's buried root and rips it from the earth like a trophy.
