Study
Etymology
芯 combines the grass radical 艹 on top with 心 (heart) below. The grass radical suggests a plant-derived fiber, while 心 (heart) reinforces the idea of a central core, like a wick at the heart of a lamp.
Meaning mnemonic
The grass 艹 on top represents the fibrous plant material of a wick, and the heart 心 below is the core that keeps the flame alive. Together, 芯 is the wick—the essential center.
Reading mnemonic
For シン, imagine the thin wick burning at the center of a candle: thin -> シン, and the wick is the thin core that sustains the flame.
