i am trying to ONLY check for grammar errors (i think this is considered a grammar error and NOT a spelling)

ei.
play.I (Word provides) play. I as a correction.
head.My (Word provides) head. My as a correction.

I tried using ActiveDocument.CheckGrammar thinking it would NOT pick up misspelled words since there is a separate range.checkspelling method but it also picks up misspelled words

anyway to isolate the different types of errors that this functions picks up?

maybe I could LOOP each error (red squiggly lines) and do an "If Instr(error, contains either . OR ! OR ?) then... ?

are these spelling/grammar errors loopable?

ei., play.I & head.My are all treated as spelling errors, quite apart from any grammar errors they might imply. You could use a wildcard Find/Replace to fix the play.I & head.My errors:
Find = ([a-z][.,\?])([A-Z])
Replace = \1 \2
