I read the word 「引き金」and the definition is:

1 小銃・ピストルなどの、指で引く発射装置の金具。

2 ある事態を引き起こす直接の原因。きっかけ。「授業料の値上げが―となって大学紛争が起こった」 起因(きいん)  ⇒類語辞書で詳しい使い方を調べる 誘因(ゆういん) 動機(どうき) モチーフ

But why is 金 connected to the meaning of "trigger"? How is "pulling money"「引き金」representative of a "gun" or "trigger"?

「金」 in 「引{ひ}き金{がね}」 does not represent "money" but "metal". "Metal" is translated as 「金属{きんぞく}」 and "metal fittings" are translated as 「金具{かなぐ}」. 「引き金」 is the part of a gun that is made of metal and is for triggering the gun to fire. In English, "trigger" also means the part of a gun as a noun, and "to cause something" as a verb.

  • Thinking 金 represented money was a silly mistake of mine. Thanks!
