jingling, tinkling
玎 centers on light, clear ringing sounds: jingling or tinkling, like small bells or delicate metal objects striking together.
玎 combines 王 (jade) with 丁, which likely contributes the sound. The character likely originally referred to the tinkling sound of jade ornaments.
The left side 王 (jade) suggests precious stone, and the right side 丁 looks like a nail. Imagine small jade pieces hanging like wind chimes, tinkling when they strike each other.
For テイ, picture a tiny jade bell making a high 'tay' sound: tay -> テイ, like the clear ring of jingling ornaments.
