I'm not sure if this the the appropriate group or if there's a FAQ (I
couldn't find one.)

I was just wondering out of odd curiosity: how does spellcheck in Word, or
any spellchecker, work?

I mean, upon detecting a word that isn't in it's dictionary, how does Word
go about suggesting a correction? My guess is that it first checks against a
database of common misspellings. After that, maybe it checks broad
categories for the suspected part of speech intended: noun, verb, adjective,
etc. in order to narrow the subsequent search somewhat.

After that, what?

Curious,
K.
