Clarity trumps probably all other considerations in the actual writing part of technical writing. (I say “probably” because anytime you use such absolutes, you can be quickly proved wrong.) In this particular case, it trumps style.
In my role as a reviewer of department communications, I recently edited a document of brief project status reports. One project’s information contained a line like this:
Project objective: Complete the merger of A’s, B’s, C’s, and D’s operations and technology resources.
Now, the use all those possessives didn’t seem right. I checked my trusty Chicago Manual of Style. CMOS 5.27 states:
Joint and separate possessives. If two or more nouns share possession, the last noun takes the possessive ending. . . . If two or more nouns possess something separately, each noun takes its own possessive ending.
Normally, I’d say that each noun’s possessed thing is separate, so each should have the possessive after all. But then again, we’re talking about a merger of those possessed things. So are they actually separately possessed? Or do A, B, C, and D all possess the merged operations and technology resources collectively?
Dilemmas, dilemmas.
So I removed the possessives. But that resulted in a garden path sentence:
Project objective: Complete the merger of A, B, C, and D’s operations and technology resources.
When you first read the sentence this way, it sounds like A, B, and C are being merged, not things that are possessed by A, B, C, and D. Or even that A, B, and C are being merged with D’s operations and technology resources. So I put the possessive endings back in to maintain clarity over style considerations.
My manager—the second-level reviewer—ended up rewriting the sentence completely, but this little episode illustrated to me how asking what version is clearest can settle other questions.
