Abstract:

Thomas Mann described the writer as somebody for whom writing is more difficult than it is for other people. Nowhere is this truer than for comma use: while most folks float along blithely putting commas in or leaving them out at whim, we agonize over every squiggle. Why? Because we understand that the presence or absence of a comma can change the meaning of a sentence. In our line of work, unclear sentences can have dire consequences for our readers. So we worry.
