Let's say you are spell checking a document and accidentally hit the "Add to dictionary" button on a misspelled word. Here's how to remove that word:
- Open WORD
- Tools
- Options
- Spelling & Grammar
- Custom dictionaries
- Select the word from the list
- Delete
- OK, OK, OK
While you are there, review the list of words you had previously added and remove as needed.
These specific steps pertain to MS Office 2003 version but are similar in other versions.
