quiet, still
闃 centers on deep, profound stillness: a quiet so complete it feels empty or deserted. The given meanings 'quiet' and 'still' both point to this absence of sound and motion.
闃 combines 門 (gate) with 狊, which likely contributes the sound and the idea of stillness or emptiness. The exact historical development of 狊 is uncertain, but the overall structure suggests a gate leading to a quiet, deserted place.
Picture a heavy gate 門 that opens onto a completely still, empty courtyard. Inside the gate, the component 狊 looks like a watchful eye 目 over a dog 犬, but everything is frozen in silence—no barking, no movement. That profound quiet is 闃.
For ゲキ, imagine the gate 門 creaking loudly in the stillness, making a sharp 'geki' sound that breaks the silence. The sudden noise 'geki' cues ゲキ, and it contrasts with the deep quiet of the kanji's meaning.
