Abbreviations

Q. I'm working with an author who insists that the proper typesetting of the abbreviations a.m. and p.m. is to set them in small caps and separate the letters with periods. Citing CMOS, I indicated that the author was incorrect because it says that if these abbreviations are set in small capitals, then periods are unnecessary. However, when I showed the author that section in CMOS, she pointed out that in the second example provided to show proper use with words such as “morning” or “afternoon,” 11:00 P.M. is shown with both small caps and periods. Is there an exception to the rule that is being exhibited in this instance? Any light you can shed on this seeming discrepancy would be appreciated.  Answer »

Q. Could you tell me the correct way to pluralize an acronym when it is the first instance and the definition that appears before the acronym is plural? Here is an example and the two options that have been suggested to me: configuration items (CIs), or configuration items (CI)s.

Q. I am editing a military memoir with frequent use of acronyms such as IED (improvised explosive device), DFAC (dining hall), MWR (morale, welfare, and recreation). Should these terms be spelled out throughout the manuscript, or is it appropriate to use the acronym after it has been described in a parenthetical on the first reference?  Answer »

Q. I am proofing an engineering document. There is a section titled “System Engineering Instruction Team (SEIT).” However, this acronym is already defined in the body of a previous section. The argument is that the section in question should simply be titled “SEIT.” However, I don’t think the section title should be reduced to “SEIT” because the reader may not know what SEIT means upon first glance at the table of contents. I say it’s okay to redefine the acronym if it suddenly becomes the title of a major section. Is it ever okay to redefine an acronym after it has already been defined?   Answer »

Q. Hello, I’m in desperate need of help with my MA dissertation. The proper abbreviation for the International Security Assistance Force’s Regional Command South is RC(S). How do I put RC(S) into parentheses after the first usage of “Regional Command South” to indicate that I will henceforth be using the abbreviated form? Right now I have “The primary allies of Regional Command South (RC(S)) . . .” This, however, does not seem correct. Can you please help?  Answer »

Q. I am editing a dissertation for a client who wants to use an abbreviation “N.” in place of “Nietzsche” in a dissertation on Nietzsche. Her advisor said this is okay. I told her it is not okay, and that abbreviations, explained in a list of abbreviations, should be used only for titles of works or for author’s names if they are used in citations but not in the text itself. Am I right?  Answer »

Q. Is it proper to define an acronym within an acronym or an abbreviation within an abbreviation? I am working on a document that contains an abbreviation that is really two other abbreviations smushed together with additional words tacked onto either side. And to top it all off, the overall abbreviation doesn’t even contain the first letter of every word in the other two abbreviations. They’ve dropped letters to make it shorter. Finally, if it is acceptable to do this sort of thing, how would I define the abbreviation or acronym on first use within the document if the two incorporated abbreviations were not previously defined in the document? Whew!  Answer »

Q. I’m editing a college-level textbook. Is it proper to eliminate the titles Mr., Mrs., etc. in running text? For example, after Mary Louise Jones is first introduced, should she be “Mrs. Jones” or just “Jones” thereafter? It seems cumbersome to repeat “Mrs.” over and over, especially if she is mentioned often.  Answer »

Q. I am editing a manuscript of a law book that uses many specialized abbreviations. There is a table of abbreviations, but we have decided to spell out each abbreviation the first time it is used in each chapter, followed by the abbreviation in parentheses. The only question I have is regarding abbreviations for commonly known words. For example, the author lists the United States in the table of abbreviations. To be consistent, I have spelled out United States the first time it is used and followed it with (U.S.). This strikes me as kind of silly, as everyone knows that the U.S. is the United States. Any suggestions?  Answer »

How would you spell out the acronym on first mention? (I am working on the second edition, and the use of the one acronym was accepted for the first edition.)  Answer »

Q. I work for a technical magazine. I’ve always been taught that when it comes to acronyms, the rule is you spell out the words first followed by the acronym in parentheses, and then use the acronym for later references in the copy. If there are no other mentions of the acronym later in the copy, then you just spell it out without the acronym in parentheses. Is this correct? My coworker is debating this with me. Thanks!!!!!!!  Answer »
