這一組就是核心畫面本身：一塊東西在液體裡鬆開，散到再也看不見。

溶解
核心畫面
Picture a sugar cube dropped into hot water. For a moment it is still a cube — one solid thing with clear edges. Then the edges , the bonds holding it together let go, and it spreads out until you cannot point to it any more. It has not been destroyed; it has stopped holding together as one thing.

一顆方糖掉進熱水裡。剛開始它還是一塊，有稜有角，你指得出它在哪。接著邊緣化掉，原本把它綁成一塊的力量鬆開了，它散進水裡，到最後你再也指不出「它」在哪。重點不是被毀掉，而是「不再抱在一起了」——原本結合成一個整體的東西鬆開、散開，於是那個整體就沒有了。英文裡不管是糖、國會、婚姻，還是一股情緒，用 dissolve 講的都是這個鬆開散掉的動作。From the word’s history
From Latin dissolvere "to loosen up, break apart" (dis- "apart" + solvere "to loosen, release"). The root idea is not "destroy" but "un-tie" — which is exactly why the same word covers sugar in water and a marriage in court.
拉丁文 dissolvere = dis-（分開）+ solvere（鬆開、解開），字面就是「把綁著的東西解開」。這解釋了一個乍看奇怪的現象：為什麼溶解和解散國會是同一個字。因為兩者都不是「打碎」，而是「解開那條把它綁成一體的繩子」。solve、absolve、solution 也都是這一家。
Wiktionary, "dissolve" (< Latin dissolvere, dis- + solvere); Online Etymology Dictionary agrees
Three branches
正式解散一個組織或關係
把「綁成一體的東西被解開」從物質搬到人的組織上：議會、公司、婚姻都是靠一份正式的約把很多人綁成一個單位，解開那份約，這個單位就散了。
dissolve; end formally · verb · C1
To formally end a parliament, a business arrangement, a marriage, or a similar official group or agreement.
解散
人與情緒的鬆開消散
同樣是「鬆開後散掉」，但對象換成看不見的東西——一股恐懼、一段友誼、一個人繃著的表情。
dissolve; fade away · verb · C1
To gradually become smaller or weaker and then disappear, or to make a feeling or quality do this.
消散
