If you’re running OS X, try this: open TextEdit, type “knowledgable” (yes, it’s misspelled on purpose), highlight it, then right-click (or Ctrl-click) it and check your suggested proper spellings. Is knswledgable in there?
The “word” is in OS X’s spelling database for some reason. It’s not recognized by Dictionary.app.
For you people with iPhones, it’s in your iPhone’s spelling checker as well.
