「guardian angel」可以想成有一個人就站在你肩膀後面，只被指派給你一個人，在你睡著的時候還醒著。這個畫面的重點不在翅膀。重點在「只有一個」：不是保護所有人的，是保護你的。也因為這樣，它前面幾乎都會帶 my、your、his；而只要有真人在剛好的時間出現，這個稱呼也可以直接交給他。From the word’s history
Wiktionary analyses the phrase simply as guardian + angel. A guardian is the person whose job is to look after another; an angel is a good spirit. The core is already sitting in those two words — a good spirit whose job is one person.
Wiktionary 把這個詞直接拆成 guardian ＋ angel。guardian 是負責照顧、保護某個人的人；angel 是宗教裡的好靈。核心意思其實就藏在這兩個字裡：一個「工作內容是某一個人」的好靈。
