“Nestle and its Crunch Bar, thought the word “Crunch” in the snack’s name, would cause confusion.”
Even without the unnecessary commas, the writing is horrible. A crunch bar has the ability to think.
Cadbury has a Crunchy Bar and there are also Crunchy Cheetos.
How would anyone expect to copywrite a verb or an adjective in common use? As part of a title such a Captain Crunch or Chocolate Crunch it is understandable as the whole phrase could be subject to copywrite.
Probably should be, “Nestle, regarding its Crunch bar, thought the word, “Crunch”, in the snack’s name, would cause confusion.”
I always put commas before and after quotation marks, when they appear in the middle of a sentence. I also tend to put them in spots where, if I were speaking, I would pause. An editor would probably blue pencil me all over the place. Oh well, tough; I love commas.
