腳下那塊地
這一組直接用核心畫面：差別只在那塊地上有什麼——什麼都沒有時講的是地面，站著一個人或一隻貓時就變成擋路。

Under your feet, on the ground you are walking on. It is used most often to say what that ground feels like: wet, soft, firm or slippery.
腳下；在腳下的地面
核心畫面
Picture the small patch of ground your own foot is pressing on right now. Not the room, not the — just that patch, and how it feels through your shoe: wet, soft, loose, cold. Everything this word does starts there. Whatever ends up in that patch takes on its character: the ground itself is described by it, a child or a cat standing in it becomes something you have to walk around, and anything left lying in it can be crushed by the next step.

underfoot 的核心畫面可以想成：你這一步正踩著的那一小塊地。不是整個房間，也不是整片山坡，就是那一塊，還有它隔著鞋傳上來的感覺——濕的、軟的、鬆的、冰的。這個字做的每一件事都從這裡開始。凡是出現在那一塊地上的東西，都會沾上它的性質：地面本身被拿來形容，站在那裡的小孩或貓變成你得繞開的障礙，而躺在那裡的東西，下一步就可能被踩爛。From the word’s history
Wiktionary gives underfoot as Middle English underfoote, underfote, equivalent to under- + foot, with cognates such as Middle Dutch ondervoet. The word is still doing exactly what its two parts say.
Wiktionary 記載 underfoot 來自中古英文的 underfoote、underfote，等於 under- 加 foot，中古荷蘭語的 ondervoet 是它的同源字。這個字到今天做的，仍然就是它兩個部分字面上說的事。

被踩在腳下
這一組把畫面加上重量和次數：不只是在腳下，而是一再被踩。兩格都只活在 trample ... underfoot 這個說法裡，單獨的 underfoot 不帶破壞的意思。

If people trample something underfoot, they step on it heavily, again and again, until it is crushed and ruined.
踩爛；踐踏
