核心畫面
Think of accrue as something that by itself while time passes. Nobody carries it in and nobody hands it over. You leave the money, the days, or the situation alone, and when you look again there is more of it than there was. That is why the subject of an accrue sentence is so often the growing thing itself, with the person who ends up holding it pushed to the end of the line.
accrue 可以想成一種「自己長出來」的畫面。沒有人把東西搬過來，也沒有誰一次交給你。時間在走，東西就一層一層疊上…更多收起
accrue 可以想成一種「自己長出來」的畫面。沒有人把東西搬過來，也沒有誰一次交給你。時間在走，東西就一層一層疊上去。像存款上的利息，像牆角慢慢積起來的落葉。你沒有動它，回頭一看，它已經比原來多了一些。所以用 accrue 的句子裡，主詞常常就是那個越長越多的東西本身，人反而被放到句尾，站在它累積的方向上。From the word’s history
Latin accrescere: ad- (in addition) plus crescere (to grow). The oldest picture is literally growing on to something that is already there.
拉丁文 accrēscō 是 ad-（再加上去）加上 crēscō（生長）。最早的畫面就是「在原本的東西上面再長一截」，和今天「本金沒動、利息卻多了」的感覺是同一個。
