Q. My client for a project that uses CMOS has asked that abbreviations ending with S be pluralized without the addition of a lowercase s. So, for example, a first reference is to “asset-backed securities (ABS)” rather than to “asset-backed securities (ABSs),” and subsequent references use ABS as a stand-in for either the singular or the plural term. I cited CMOS 7.15—but the client is “used to seeing” abbreviations without the added s and says it “looks awkward.” I accept that the client gets to call the shots, so I acceded to the request. Did I accede too readily?

A. You did your job—there’s just no saving some people from themselves.
