Manuscript Preparation, Copyediting, and Proofreading
Q. I transcribe audio recordings verbatim, and sentences cannot be changed to leave out a false start. In this situation, is the word after the dash capitalized? “The—when you were turning into the apartment complex, was there enough room?”
A. Since The is a false start, the word when effectively begins a new sentence and may be capped to show that. It’s probably not a good idea to build a rule around this, however; rather, decide case by case.
