Q. I have a hyphenation question that I wasn’t able to resolve after reading CMOS or the Q&A page on your website. I am in a debate with a fellow attorney about the proper hyphenation for the phrase “explicitly-defined” when used in the context of “an explicitly-defined rule governing adoptions.” My colleague insists there should be no hyphen between “explicitly” and “defined.” I think that there should be a hyphen between the two words.

Q. Dear Chicago, I’m in a debate with my 73-year-old publisher. I lost my AP Style book in a recent move and I can’t remember the rule for putting hyphens in a person’s age. My publisher says it is only used when the age is a modifier. I say it needs to be used when it is a noun as well, such as: “The healthy 18-year-old jumped in his car . . .” He claims it is only used in a sentence similar to this: “An 8-year-old boy.” Please let me know which is correct so I can end this debate and put this magazine to bed! Thank you, Missouri. Answer »

Q. Some authors in the company for which I copyedit have been using an en dash, rather than a hyphen, for the negative sign in negative numbers, i.e., –3 versus -3. Some of our required fonts exaggerate the difference, and occasionally this results in negative signs of varying size in our technical documentation. I would prefer that all authors use the hyphen to create a more consistent look. As CMOS is this company’s style reference guide, I have searched through it for a recommendation regarding this topic but have not found one. Does CMOS have a preference? Answer »
