Unlearn a Word in macOS' Dictionary

Have you ever right clicked on a word that was spelled incorrectly and instead of clicking on the properly spelled word, you selected Add to Dictionary?  Here's how to remove that word!

sudo nano ~/Library/Spelling/LocalDictionary

In that file, you'll find your misspelled word and can remove it from the list!  Easy!

Of course, you can use a different editor, if you'd like.

Going forward, you could...

• Backup this file
• Add words to this file in bulk
• Develop a basic Bash script to add words to this file from a terminal
