More Reps!

This workout centers on the first half of section 3, “Compounds Formed with Specific Terms,” in our extended hyphenation table under paragraph 7.96 in CMOS 18.

Advanced editors might tackle the questions cold; learners can study that part of the hyphenation table before answering the questions. (Workout 23, “Hyphens, Part 3b,” covers the second half of section 3.)

Subscribers to The Chicago Manual of Style Online may click through to the linked sections of the Manual. (We also offer a 30-day free trial of CMOS Online.)

Note: Dictionaries and style guides sometimes disagree. These questions are designed to test your knowledge of The Chicago Manual of Style, which prefers the dictionary at Merriam-Webster.com. Other style guides may follow a different dictionary.
