When I use Microsoft Word I find I am constantly being “corrected” for the grammatical mistake of using ‘which’ as a clause in a sentence, when apparently I should either be putting a comma after it or changing it to ‘that’. For example:
Sentence A: “The Straight Dope is a world-class board which I am proud to be a part of.”
Apparently this is grammatically incorrect, and it should always be either:
Sentence B: “The Straight Dope is a world-class board, which I am proud to be a part of,” or
Sentence C: “The Straight Dope is a world-class board that I am proud to be a part of.”
Is Sentence A really grammatically incorrect? Do you really have to use a comma every time you use ‘which’ in this type of clause? If so, why don’t you have to use one after ‘that’? The whole thing just strikes me as being a bit odd, and it’s something that seems to crop up every time I write something in Word!
