讓人進入一個空間
最貼近字根的一支：替某人開門，放他進入一個空間。從實體的場地，延伸到團體、醫院這些抽象一點的『裡面』。

To let someone go into a place such as a stadium or theatre, often to watch something.
准許進入
核心畫面
Picture a at a gate deciding whether to let someone or something through. That act — to let in — is the root of admit. You can let a person in through a door, or let a fact in through the guard you keep up.

可以想成門口有個守門的人，決定要不要放你通過。admit 的核心畫面比較像這個『放進來』的動作——可以放一個人進場，也可以放一句話、一個事實進到你心裡。From the word’s history
From Latin admittere 'to let in, allow to enter,' from ad- 'to' + mittere 'to send, let go.' The physical 'let in' is the root; 'concede that something is true' (early 15c.) is letting a statement in past your resistance.
來自拉丁文 admittere（放進來、准許進入），由 ad-（朝向）加 mittere（送出、放行）組成。原意就是實體的『讓…進來』；後來『承認某事屬實』其實是把一句原本擋著不想接受的話放進門。

Three branches
讓事實或說法進來（承認）
把『放進來』從人搬到話語：本來擋在門外、你不太想接受的事實，最後還是讓它進了門。這個『放行一句話』就是中文的承認。
admit, acknowledge · verb · B1
To agree that something is true, especially when you do not really want to.
承認
法庭採納證據
又回到最實體的『讓…進來』，只是進來的是一份證據，進的地方是審判紀錄。法官替證據開門，它才能被用。
admit evidence in court · verb · B1
To officially allow a piece of evidence to be used in a court of law.
採納(證據)
