One way to picture it: a hand pressing something down from above so it cannot rise up — the thing is still there underneath, pushing, but it is not allowed to come out.
From the word’s history
From Latin suppressus, past participle of supprimō "press down or under", from sub- "under" + premō "press" — the same premō that gives press, pressure, and compress.
來自拉丁文 supprimō，由 sub-（在下面）+ premō（壓）組成，字面就是「往下壓、壓在底下」；press、pressure、compress 都是同一個 premō 的家族。知道這一點之後，suppress 的四個用法就不是四件事，而是同一個「往下按」的動作，作用在不同的東西上。
