KanjiJLPT N2
Pillar

pillar, post, cylinder, support

Mnemonic

The lord ordered the mightiest tree in the forest felled to become the central pillar of his grand hall. He carved his royal seal deep into the tree trunk, declaring this pillar the very heart of his domain—without it, the whole castle would crumble.
Additional thoughts
Picture a feudal lord hugging an enormous wooden column that still has bark on it—half tree, half architecture. The lord's identity is literally carved into it, binding ruler and structure together.
Quick recall
A lord turns a great tree into the central pillar of his castle.
