You can have as many custom dictionaries as you like; they are just text
files, and you can add words to them as needed. The specific custom
dictionary must be selected as the default if you want added words to go
into it. See the Help topic "Create and use custom dictionaries."

If your wife would prefer to buy a medical dictionary add-in, one
possibility is Stedman's. See

My wife is getting into medical transcription and a specialized medical
spelling checker would be most useful. Does anyone know if such a thing is
available for Word? How easy is it to create your own specialized spelling
checker?

thanks - david
