把「真的如此」推到底（強調）
這一族直接承接核心：都是拿 truly 去堵住「說的」和「真的」之間的縫隙，把一件事的真實程度推到滿。差別只在放在哪裡、搭配哪個片語。
truly (intensifier) · r · B2
Used before an adjective to show that what you are saying about something is really and completely true.
真正地
核心畫面
You can picture 'truly' as the word you put in front of something to say: this is not just close to real, it is all the way real. 'She was truly happy' means there is no gap between the word 'happy' and what was actually inside her.

可以想成：truly 是你放在一句話前面、用來把「真實」推到底的字。說某件事 truly 如此，意思是它跟事實之間沒有縫隙——不是差不多真，而是完全就是那樣。核心畫面比較像：一個字貼緊了它所描述的真實，中間沒有任何水分。From the word’s history
'Truly' is 'true' + '-ly'. 'True' goes back to Old English treowe 'faithful, steadfast', from a Proto-Germanic root meaning 'having good faith' (the same root family as 'trust' and 'tree' — the idea of being as steadfast as an oak). So 'truly' first meant 'in a faithful, steadfast way', and only later 'in a way that matches the facts' — which is why the word still stretches across both being faithful in the heart (sincerely) and being faithful to the facts (accurately).
truly 是 true 加上 -ly。true 來自古英語 treowe「忠實、堅定」，源自原始日耳曼語一個「懷有誠信」的字根——和 trust（信任）、tree（樹）同一族，背後的意象比較像「像橡樹一樣穩固不移」。所以 truly 最早是「以忠實、堅定的方式」，後來才變成「符合事實地」。這條線索也解釋了為什麼這個字能同時橫跨「對內心忠實」（真心地）和「對事實忠實」（確切地）。

Three branches
忠於內心 · 忠於事實
這一族最貼近字根「忠實」。核心比較像「沒有縫隙的真」，而這裡問的是：對什麼忠實？一邊是對自己的感受忠實（真心），一邊是對外在的事實忠實（確切）——同一個「忠」字分成向內和向外兩個方向。
sincerely · r · B2
In a way that comes from your real feelings; sincerely.
真心地
書信裡的固定用語
這一族是「忠實」意思凍結在一句書信客套話裡的化石。'Yours truly' 字面是「忠實地屬於你的（人）」，原本是署名前表示誠意的結尾，後來整句被當成一個現成的招牌，甚至拿來俏皮地指自己。
Yours truly (letter closing) · r · B2
Used in 'Yours truly' to close a letter politely, just before you write your name.
