核
Mnemonic
Split open a tree's fruit and deep inside you discover what looks like a crumpled waste bag wrapped tightly around something hard. Peel that waste bag away and there it is — the nucleus, the essential stone pit at the very center of the fruit.
Additional thoughts
Visualize a peach hanging from a tree. Cut it open: the flesh surrounds a wrinkled, bag-like husk clinging to the hard pit. That husk is the waste bag, and the pit is the nucleus. Tree + waste bag = nucleus.Quick recall
A tree's fruit hides a waste bag husk around the hard nucleus pit inside.Details
The keyword for 核 is nucleus. This kanji refers to the core or central part of something, much like the nucleus of a cell or an atom.
