可以想成這個畫面：你朝著臉應該在的位置看過去，那裡什麼都沒有。人的輪廓還在，所以那個「沒有」特別明顯。其他用法都是從這裡長出來的。臉是我們用來分辨誰是誰、看懂對方意思的東西。把臉拿掉，剩下的就是兩件事：大家都長得一樣，以及一場少了訊號的對話。From the word’s history
The source's etymology tree shows the word as face plus the suffix -less, with face going back through Middle English to Latin faciēs, and -less from Old English -lēas. So the literal reading, having no face, is simply the parts read out.
來源的詞源樹顯示這個字是 face 加上字尾 -less。face 經由中古英文上溯到拉丁文 faciēs，-less 來自古英文 -lēas。所以「沒有臉的」這個字面義，其實就是把兩個零件直接唸出來。
