震える
ふるえる · furueru · JLPT N3 · verb-ichidan
to shiver
❄️ furueru sounds like fur: with no fur, you shiver
The kanji 震 means quake. It also appears in 地震 (jishin, earthquake), which is ground + shake. So 震える covers a shiver from cold or fear and also the ground shaking.
震 — rain radical 雨 + chen 辰 (phonetic)
A semantic-phonetic compound: 雨 'rain' gives the meaning (weather/sky phenomena), while 辰 supplies the sound. Originally referred to thunder and the shaking it causes, then extended to mean 'shake, quake, tremble' as in earthquakes (地震).
