KanjiJLPT N3
Divide

proportion, comparatively, divide, cut, separate, split

Mnemonic

A wild slash of the knife does nothing but harm—splitting skin, drawing blood. But a master chef channels that same destructive force with precision to divide ingredients into flawless, equal portions. What once caused harm now divides with purpose.
Additional thoughts
Visualize a chef transforming a harmful slash into controlled, precise cuts that divide a roast into ten perfect pieces. Harm + Knife = Divide. The same blade, different intent.
Quick recall
A knife that once caused harm now divides with masterful precision.
