Chicago Style Workout 22:
Hyphens, Part 3a

More Reps!

This month’s workout, “Hyphens, Part 3a,” centers on CMOS 17, paragraph 7.89 (our famous hyphenation table), and in particular the first half of section 3, “Compounds Formed with Specific Terms.”

Advanced editors might tackle the questions cold; learners can study the first half of paragraph 7.89, section 3, of the Manual before answering the questions. (“Hyphens, Part 3b” will cover the second half of section 3 in a future workout.)

Note: Dictionaries and style guides sometimes disagree. These questions are designed to test knowledge of The Chicago Manual of Style, which prefers Merriam-Webster’s Collegiate Dictionary, 11th edition. Other style guides may follow a different dictionary.
