It’s good to eject yourself from a burning spaceship (if you happen to have an escape pod and a nice small planet to land on), but if a teacher ejects you from class, well that’s not so good.
Eject comes from “jectere,” the Latin word meaning throw, but the “e” means out. If you want to say, “throw the rascals out!” in only one word, you should choose, “eject!” The opposite of eject is inject. Thinking about the nurse throwing the measles vaccine into your arm makes that doctor’s visit seem a little less friendly.
