Spell checking a document and I have inadvertently added a misspelt word into my dictionary. This might not be so bad if its a goof that you aren’t likely to repeat, by what about a word you ALLWAYS speel incorrectly?
It is there forever! Or is it?
1. Open TextEdit (its in your applications folder)
2. Type the goof again.
3. Right mouse click on the word and choose Unlearn Spelling.
