What Is a Prescriptivist Editor?

If you work with words, you’re probably familiar with the related but supposedly antithetical concepts known as prescriptivism and descriptivism. And people take sides. Either you’re a stickler (you’re a prescriptivist) or you go with the flow (you’re a descriptivist).

Commas between Compound Predicates

We learn from CMOS 6.23 that “a comma is not normally used to separate a two-part compound predicate joined by a coordinating conjunction.” In other words, when the subject isn’t repeated after a word like “and” or “but” in a compound sentence, a comma is usually omitted.
