Abbreviations Overview

Building Chicago-style strength

This workout centers on paragraphs 10.1–10.12 in CMOS 18. (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.)

Remember: The workouts are all about Chicago! If you’re an expert in MLA, AP, or New York Times style, you might be surprised to find that your instincts don’t quite match Chicago’s. That doesn’t mean your answer is necessarily “wrong”—it just means it isn’t Chicago style.

Note: In this quiz, as in the Manual, the word abbreviation may also refer to initialisms, acronyms, and contractions.

Now updated to refer and link to the 18th edition.
