Capitalizing Hyphenated Words in Titles

In a recent business writing class, a careful editor questioned me about capitalizing up in Writing Tune-Up for Peak Performance. In a hyphenated compound word, shouldn't a little word like up be lower case?

As usual, the answer is that it depends on whose style you follow.

I like the style promoted by The Gregg Reference Manual because it is simple and straightforward. Regarding hyphenated words, Gregg says, "In a heading or title, capitalize all the elements except articles, short prepositions, and short conjunctions." In Gregg, short means fewer than four letters.

Following the Gregg way, both parts of Tune-Up are capitalized because up is an adverb in that expression. The same is true of Follow-Up, Runner-Up, Shoo-In, Run-In, Trade-In, Set-To, Turn-On, and Take-Off. All those little ups, ins, tos, ons, and offs are adverbs, and Gregg capitalizes adverbs in titles.

The Microsoft Manual of Style for Technical Publications makes capitalizing hyphenated words a bit more complex. According to Microsoft, you should capitalize the second word of a compound word in a title only if "it is a noun or proper adjective, it is an 'e-word,' or the words have equal weight." Microsoft gives these examples: E-Commerce, Cross-Reference (words of equal weight), Run-Time, Add-in, How-to, Take-off. (Gregg would render those last three as Add-In, How-To, and Take-Off.)

The Chicago Manual of Style takes a more complex approach to capitalizing hyphenated words. It agrees with Gregg that adverbs should be capitalized. Yet it recommends Run-in and Take-off because in and off are short and unstressed. It suggests Hand-me-downs for the same reason. Beyond that, Chicago does not capitalize the second part of a spelled-out hyphenated number (Twenty-first and Two-thirds). I like its approach in a final rule: "Break a rule when it doesn't work." Well done, Chicago.

If you had not already recognized the value of a company or team style sheet, these varying rules make a strong case for creating one. No more stressing over which hyphenated words should be capitalized in a title! Just stress once, decide, and record your decision.

I hope this review was helpful. Next question?

This is something I've wondered about, and it's good to know what the various reference manuals say. Thanks for saving me the work of looking them all up! Our style generally goes to using capitals in hyphenated words because it looks better in headings. However, I also think CMOS is so sensible when they advise breaking rules if something doesn't look right (I love their monthly FAQs - grammar and humor together!).

I also love CMOS's advice to break a rule that doesn't work. In my opinion, it's better for text to flow well and to look and sound correct to the majority of people than to be technically correct, but appear strange or stilted.

How timely is this? I was just reviewing a letter and noticed that in one place they had put Co-Chair and in another Co-chair and I wasn't sure which one was right, but I did know that whatever it was, it should be consistent throughout the letter.

After reading this post, I like the Gregg answer and will change it to Co-Chair.

Thanks as usual,

Patricia

Hi, Val, Stephanie, and Patricia.
Thanks for commenting on the niceties of business writing!

Patricia, I am glad you brought up "Co-Chair." Based on the rules I reviewed, I believe all three manuals would capitalize both parts in a title.
