Usage and Grammar

Q. I cannot find a reference to this in my Manual: because versus since. I have been tutored that because is used for instances of cause/effect and that since is for time. However, one of my authors is a scholar who contends that “since denotes a state of being based on a relationship. . . . Because implies causality between one aspect of that relationship and the other.” Can you explain this to me more clearly or refute it altogether?

Q. I work for an insurance company, and one of our beloved underwriters is disputing an exclusion in our policy that specifies “while piloting or serving as a crewmember in a plane.” She wants it to read, “while piloting or serving as a crewmember on a plane.” I can think of ways to defend both, but I’d love to know which is correct.

Q. We are having a bit of a debate down here—in a manuscript, one of our authors refers to a person who keeps a journal as a “journaler.” The author prefers “journaler” to “diarist” because she feels that they are two separate things. The copyeditor wants to change “journaler” to “journalist” (the second definition of “journalist” is “a person who keeps a journal”), but I think that would be confusing to a reader. “Journalizer” appears in Merriam-Webster but doesn’t seem right either. Any opinions?

Q. When is it correct to use “if” and when is it correct to use “whether?” Thank you.

Q. Recently I was trying to determine (once again) whether subjects should be considered singular or plural when they are of the following form: rock(s). Personally, I think the simplest approach would be to treat it as any other parenthetical note within a sentence: it’s a note to the reader, but it should not affect the grammar of the sentence. Therefore, “rock(s)” would be treated as singular, not plural, and certainly not singular and plural. I looked through CMOS but could not find a solution. I guess my actual question is, is there a flaw in my reasoning, and if not, could Chicago recommend it?

Q. Which is correct? “Most important, you enable your students to pursue their passions” or “Most importantly, you enable your students to pursue their passions.”

Q. If words in parentheses would turn a singular subject into a plural subject, should the verb (outside the parentheses) be plural? I’m wondering specifically whether “applies” should be “apply” in this sentence: A case such as this illustrates a broader category in which justice (and, therefore, injustice) no longer applies.

Q. I’m trying very hard to understand how through and to are different, as in “Monday to Friday” or “Monday through Friday.” Do they mean the same thing? To complicate matters, if an en dash is substituted (as in “Monday–Friday”), could the meaning be either through or to? I’m editing a paper that contains hundreds of date and number ranges. Sometimes the writer spells out to or through, but most of the time, he uses an en dash. I’ve read 6.78 a gazillion times and need further clarification. Thanks!

Q. I wonder how appropriate it is to use the word one to refer to an undefined person (probably the reader) in a manuscript that I prepare for a scientific journal. For example: It could be argued that one should consider this.

Q. I’m in a quandary regarding gender pronouns. In an economics paper (on first-price auctions) that I am editing, the author has defined the actors in his proposition like this: “The female and male pronouns are used for weak and strong bidders, respectively.” Is there any exception where gender-biased language is allowed for ease of expression? What do you recommend?
