穿進去、穿過去
這一組最貼近字面：擋在前面的是實實在在的東西——木頭、衣服、屋頂，或是一排防守的球員。共同點是它沒有被擋住。
adjective · C1
Able to get into or through something without much trouble — used about things like cold air, rain, oil, light, or a tool made to go deep into a surface.
穿透的
核心畫面
Picture something meeting a surface and not stopping at it. Cold air finds the gap in your coat; oil sinks into the wood instead of sitting on top. The word is not about being strong — it is about getting in. Once you hold that picture, the other uses are just different surfaces: the polite answer a question goes past, the wall of defenders a pass goes through, the body itself.

可以想成一個東西碰到表面，卻沒有停在那裡。冷空氣找到外套的縫就鑽進去；油不是浮在木頭上，而是吃進去。這個字的重點不是「力氣大」，是「進得去」。抓住這個畫面之後，其他用法只是換了要穿過的東西：問題穿過的是客套的說法，傳球穿過的是一排防守的人，另一個用法穿過的則是身體。From the word’s history
From Latin penetrāre 'to penetrate', through Medieval Latin penetrativus and Middle English penetratyve — so the idea of going in has been in the word from the start.
字典把它一路追到拉丁文 penetrāre（進入、穿透），經過中世紀拉丁文 penetrativus 和中古英文 penetratyve 才進到現代英文。也就是說，「進得去」從一開始就是這個字的內容，不是後來才加上的。

Three branches
看穿表面
同樣是穿過去，只是擋在前面的東西換成了「表面的說法」：漂亮的官方回答、看起來合理的解釋。一個 penetrative 的問題不會停在那裡。
adjective · C1
Showing that someone understands things quickly and deeply, and can see what is really going on under the surface — used about questions, remarks, and pieces of writing.
深刻的
進入身體：只活在 penetrative sex 裡
還是同一個「進入」的字面意思，只是對象是身體。要注意它不能拆開：這個意思不能單靠 penetrative 一個字成立。
