Remove "alright" from standard.dic?

The word “alright” is not all right, in point of fact, is it all wrong. It is not a real word, but yet the standard English dictionary used to check spelling passes over it without highlighting it as a misspelled word.

I know how to remove entries I have added to the standard and custom dictionaries, but not how to edit the entries the dictionary came with.

Anyone know how to do this?

Create a user-defined exception dictionary.
