濕布本身
這是字面上的意思，也是另外兩個意思的出發點。
verb · B2
To make something a little wet — not soaked through, just wet enough that it feels damp and becomes softer, cooler, or easier to work with.
把…弄濕（只是微濕）
核心畫面
One way to hold dampen: a damp cloth laid over something. Water in small amounts does not destroy what it touches — it takes the sharpness out of it. Lay it on a fire and the fire stops burning . Lay it on a drum and the drum stops ringing. Nothing here is stopped or removed; it is only turned down, because something has soaked up the energy that was in it.
dampen 可以想成一塊濕布蓋上去的畫面。少量的水不會把東西毀掉，它只是把那股勁收掉。蓋在火上，火就燒不旺了。蓋在…更多收起
dampen 可以想成一塊濕布蓋上去的畫面。少量的水不會把東西毀掉，它只是把那股勁收掉。蓋在火上，火就燒不旺了。蓋在鼓面上，鼓就不響了。這裡沒有任何東西被拿走或被切斷。它只是被調小了，因為原本那股能量，被什麼東西吸進去了。From the word’s history
The supplied source gives the word as damp plus the ending -en, which forms verbs meaning to make something become that way. So dampen is literally to make damp, and the two other senses can be read as that same wet cloth laid on a feeling or on a sound.
來源給的字源很直接：damp 加上 -en。-en 這個字尾的作用是「使變成那樣」。所以 dampen 字面上就是「使變濕」。另外兩個意思，都可以當成同一塊濕布，只是蓋的對象換成了情緒，或換成了聲音。
Wiktionary entry for dampen (kaikki extract supplied in the evidence packet, source_ref kaikki:3f6f69a190036ae4:288559670): From damp + -en.

蓋在情緒與熱度上
