Question ID: 724043
The Microsoft Word spelling checker seems to operate by straight
dictionary lookup.  If a word is in the dictionary, it doesn't get
flagged during a spelling check; if it isn't in the dictionary, it
does get flagged.  Is there anything more to the Word spelling checker
than that?  Is there some algorithm, for example, for how it ranks
suggestions for words it doesn't recognize?  Also, anything you can
tell me about the history of the Microsoft Word spelling checker--for
example, if it's improved at all over the years--would help.   Thanks.
There is no answer at this time.

suggestions for words it does not recognize.
