核心畫面
You can think of faithfully as someone standing exactly where they said they would stand, and still being there when you come back much later.

「faithfully」可以想成：一個人答應站在那個位置，你隔了很久回來，他還在原地。不同用法裡，他守著的東西不一樣：可能是一個人，可能是一個習慣，也可能是原作本來的樣子。但底下的畫面是同一個：沒有偏離，也沒有走樣。所以中文有時候翻「忠心地」，有時候翻「從不間斷地」，有時候翻「忠實還原地」，其實講的是同一件事。From the word’s history
Wiktionary records faithfully as Middle English feithfulli, that is faithful plus -ly, built on faith. Keeping faith with something is the idea that still sits under every modern use.
Wiktionary 記錄 faithfully 來自中古英語 feithfulli，也就是 faithful 加上 -ly，字根是 faith（信）。今天不管守的是一個人、一個習慣，還是原作的樣子，底下都是同一件事：守住那份信。這是概念上的連結，說明它今天的用法為什麼能收在一起。
Wiktionary (kaikki extract, source_ref kaikki:3f6f69a190036ae4:1025563559:8807): From Middle English feithfulli, equivalent to faithful + -ly.
