One way to picture it: a tight string is pulled back and let go. The sound that follows is short, bright and a little sharp, and it shakes for a moment before it dies. The evidence packet says the word is simply that sound. From there, everything else is the same sharpness moved somewhere new — into a voice, or onto the tongue.
From the word’s history
The evidence packet marks the word as onomatopoeic — it imitates the sound itself — and compares older words in the twinge family. It offers no further route to the voice or taste uses, so those links are read here as pictures, not as descent.
手上的資料把這個字標成擬聲：字的聲音就是那個聲音，並拿 twinge 那一家的老字來比對。資料沒有說明「嗓音」和「味道」這兩支是怎麼長出來的，所以這裡只把它們當成同一股銳利的延伸畫面，不當成字源上的傳承。
