Think of a mind that has slipped its rope. The person is still talking, still moving, but nothing is being held back and nothing quite matches the room. A fever can that rope, and so can news too good to take in. Delirious names the loose state itself, and leaves the cause to the words around it.
delirious 可以想成一顆繩子鬆掉的腦袋。人還在講話，還在動，可是沒有東西被收著，講的內容也跟現場對不太上。讓繩子鬆掉的可能是一場高燒，也可能是一個太好、一時收不下的消息。這個字說的是那個「鬆掉」的狀態本身，至於是什麼把繩子弄鬆的，交給旁邊的字去講。
From the word’s history
Wiktionary gives the word as delirium plus the adjective ending -ous, and points to Latin delirus, meaning silly or crazy. So the adjective simply names a person who is inside the state called delirium.
維基詞典說這個字是 delirium 加上形容詞字尾 -ous 組成的，並提到拉丁文的 delirus（糊塗、發昏）。所以它的意思就寫在形狀裡：處在 delirium 這個狀態裡的人。先認得名詞 delirium，形容詞就不用另外背。
