Radical Analysis
The kanji 校 is composed of two parts:
- Radical: 木 (ki - tree/wood): Historically, schools were often built of wood, or perhaps the radical refers to the wooden tablets used for record-keeping in ancient times.
- Phonetic component: 交 (kou - to cross/exchange): This provides the sound "kou." In ancient times, people would "cross" paths or "exchange" knowledge at a school, linking the phonetic component to the meaning of a place of learning.
Mnemonic
Imagine a tree (木) standing in the center of the schoolyard. Underneath it, students are crossing (交) paths as they walk to their classrooms. Where do they cross paths? At the school (校).
