Do you want to delete a word that you erroneously added to your custom
dictionary? If yes, then quoting from Word help:
1. On the Tools menu, click Options, and then click the Spelling &
Grammar tab.
2. Click Custom Dictionaries.
3. Select the dictionary you want to edit. Make sure you do not
clear its check box.
4. Click Modify.
5. Do one of the following:
* To add a word, type it in the Word box, and then click Add.
* To delete a word, select it in the Dictionary box, and then
click Delete.
* To edit a word, delete it, and then add it with the
spelling you want.
Or do you want to delete a word that is included in Word's main
dictionary? If yes, then you can't, but you can create a custom
"exclude" dictionary containing correctly spelled words that you want
Word/Office applications to flag as being misspelled. See
