真的被埋起來的寶
這是字面本身：東西真的被藏起來、真的被挖出來。

無主埋藏物
核心畫面
You can picture someone lifting a lid on something that was shut away and forgotten, and finding it packed with good things — so the word always carries the moment of discovery, not just the pile itself.
可以想成有人掀開一個被關起來、久沒人動的東西。裡面滿滿都是好東西。重點不只是「東西很多」，而是「被翻出來的那一刻」。…更多收起
可以想成有人掀開一個被關起來、久沒人動的東西。裡面滿滿都是好東西。重點不只是「東西很多」，而是「被翻出來的那一刻」。這個字永遠帶著挖到寶的驚喜。最原本的畫面是地下埋著的一罐金銀幣，後來這個畫面被搬到任何值得一挖的地方：抽屜、網站、市場、舊筆記本。所以無論講的是真的寶藏還是比喻，發現感都在。From the word’s history
From Anglo-Norman tresor trové, "found treasure", a calque of Latin thesaurus inventus; the past participle trové ("found") was later read in English as a noun, which is why the discovery is built into the word.
來自盎格魯諾曼法語的 tresor trové，意思是「被找到的寶藏」，這又是拉丁文 thesaurus inventus 的仿譯。原本 trové 是過去分詞「被找到的」，進了英文之後被當成名詞用，所以今天看起來像兩個名詞。這條線索正好解釋了為什麼這個字的「發現感」拿不掉。
