You can think of eject as one quick push from inside to outside. Something is sitting in a space — a hall, a seat, a job, a machine, a body — and a force sends it out. The thing that leaves does not choose to leave, and it goes fast.
eject 可以想成一個「從裡面被推到外面」的動作。有樣東西原本待在某個空間裡：大廳、座位、職位、機器、身體。然後一股力量把它送出去，又快又不商量。走的那一方通常沒得選。不管出去的是人、火山灰還是光碟，這個畫面都沒有變過，只是力氣大小不同。
From the word’s history
The evidence packet traces eject to Latin ēiciō, from ē- (a form of ex, 'out') plus iaciō ('to throw'), reaching English through Middle French éjecter. 'Throw out' is close to what the modern word still does.
資料裡的字源說 eject 來自拉丁文 ēiciō，由 ē-（ex 的變體，向外）加 iaciō（丟）組成，經中古法文 éjecter 進入英文。字面就是「往外丟」，和今天的用法幾乎重疊。-ject 這個部分在 reject、inject、project 裡也看得到。
