"Sara" wrote in message

In Microsoft word, how do I correct words that I have added to my
correctly
spelled words which I accidentally spelled wrong by mistake? (For
instance,
typing too fast or else didn't take the time to look it up and it was not
right). Say, I typed the word "docter" and it was underlined as being
misspelled in red. I clicked on it and said "add" and later realized it
really is spelled "doctor". How do I delete the spelling of "docter" now?
