Hyphens, En Dashes, Em Dashes

Q. If court testimony is being quoted and the speaker does not often use correct grammar (repeats words, speaks in sentence fragments or sentences that don’t logically follow, etc.), is it okay to change it extensively and use brackets to indicate the changes? Would a general disclaimer work?

Q. My question is regarding page numbers in references. If we have pages ranging from 315 to 317, it is my understanding this should read as 315–7. Now let’s say a journal article is from pages 310 to 319. Does it matter that there is a zero in the beginning page number? Is the proper format 310–9 or 310–19? Someone has informed me that if a zero occurs in the beginning page, we must skip a number back in the ending page. That would mean 310–19, rather than 310–9.

Q. I am editing a collection of poems. My poet is inclined to use ellipses and em dashes extensively and incorrectly. I argued that this will detract from the manuscript and be distracting for readers. She argued that it’s a style thing and I shouldn’t change it. Who is right? Does the poet get complete license?

Q. For Chicago style, is there a mandate on whether a paper clip or staple should be used?

Q. Dear CMOS: My author uses 9/11 as a shorthand to refer to the September 11 attacks. When this is being used in the phrase “post-9/11 world,” wouldn’t an en dash be more appropriate than a hyphen because post has to bridge 9/11, which is shorthand for two words?

Q. Hello, I've tried to grasp the rule on hyphenating a couple of words I'm confronted with; could you please confirm I'm right in my reasoning: nontoxic (“non-toxic” would look better); nonsmokers (“non-smokers” would look better); noneicosanoid functions (“non-eicosanoid” would look better; nonphosphorylated form (“non-phosphorylated” would look better).

Q. I’m seeing this particular use of hyphens: low-to-moderate income families. I don’t think it’s correct, but it’s becoming so common that I’m beginning to wonder if I missed something.

Q. I was not able to find this in CMOS anywhere: how do you hyphenate a word that has both a prefix and a suffix? For example, should “seminationwide” have any hyphens?

Q. Should “64 Slice Cardiac Computed Tomography Angiography Program” be hyphenated “64-Slice”?

Q. Obviously, two adjectives separated by “and” need not be hyphenated, as in “Brackett Omensetter was a wide and happy man.” But how about suspended compound nouns, for example, “city- and state government” or a musician’s “recording- and practice space”? Need the first modifier have a suspended hyphen? I vote hyphen, myself, but I’ve been called to account and could find neither backup nor smackdown in the Chicago Manual.
