second hand
adverb核心畫面
Picture something being passed along a line of hands. The first hand had it new, or was there when it happened. By the time it gets to you, yours is the second hand in the line: the jacket has already been worn, the story has already been told once, the experience belongs to someone who is now describing it to you.

可以想成東西沿著一排手傳下來。第一雙手拿到的是全新的，或者那個人本來就在現場。傳到你手上的時候，你是第二雙手：外套已經有人穿過，消息已經有人講過一輪，經驗是別人的，你拿到的是他的描述。一種想法是：second hand 不是在說「舊」，而是在說「中間隔了一個人」。所以它可以用在東西上，也可以用在消息和經驗上。From the word’s history
The source splits the phrase as second (the ordinal number) plus hand in its older sense of a party or person involved in something. So second hand is literally 'the second party' — the one who gets the thing, or the news, after somebody else has had it.
來源把這個詞拆成 second（第二）加 hand，而這裡的 hand 是它比較舊的意思：牽涉某件事的一方、一手。所以字面就是「第二方」——東西或消息先到第一手，再輪到你。這條線索正好對上今天的三個用法：買到的東西、聽到的消息、知道的經驗，都是別人先有、你後有。

消息和經驗經過別人的口
同一排手，只是傳的東西從物品換成了看不見的東西：一則消息、一整段經驗。既然中間隔了一個人，你講出來的時候自然會留一點餘地。
r · B2
If you hear or learn something second hand, the news did not come to you from the person it is about or the person who first said it; it reached you through somebody in between.

second hand

Picture a clock face with three pointers on it. Two of them look still; the thin one is the only part of the clock you can actually watch moving, or sliding from mark to mark and coming all the way round once a minute.
可以想成一個有三根針的鐘面。時針和分針看起來像是停著的，只有那根細細的針看得出來在動。它一格一格跳，或者平順地滑過去…更多收起
可以想成一個有三根針的鐘面。時針和分針看起來像是停著的，只有那根細細的針看得出來在動。它一格一格跳，或者平順地滑過去，一分鐘剛好繞完一圈。一種想法是：這個字裡的 hand 不是「手」，而是「指針」；second 也不是「第二」，而是時間單位「秒」。所以它跟「二手」的 second hand 只是長得一樣，來路完全不同，念起來重音也不同。From the word’s history
The source gives a different split for this word: second in its time-unit sense plus hand meaning the pointer on a dial. That is why the stress falls on SEC-ond here, and why it has nothing to do with the second hand that means used.
來源給這個詞的拆法不一樣：second 是時間單位「秒」，hand 是錶盤上的「指針」。所以字面就是「數秒的那根指針」。這也解釋了重音為什麼落在前面的 SEC-ond，以及它跟「二手」那個 second hand 為什麼毫無關係。
