I accidentally added a word I'm forever mis-spelling into Eclipse's spell-checker dictionary. How do I get it back out again?
回答1:
Eclipse puts the words you add into a text file, AKA the User defined dictionary.
You can find the location of this file at Window -> Preferences -> General -> Editors -> Text Editors -> Spelling -> User defined dictionary.
I believe that it's not set up by default - the first time you use the Add to dictionary feature it asks for the user dictionary location.
Open up the file in a text editor and remove the word you don't want. You'll probably need to restart Eclipse before it recognises the word as misspelled again (i.e. before it will re-read the user dictionary file).
回答2:
As mentioned in bug 51445, the user defined dictionary is any text file, by default with a '.dic' extension (but you can use any or no extension if you like).
The help page help you to locate that file.

As mentioned in bug 111265 (comment 2), you need to relaunch eclipse...
