Hyphens and Compounds and Copy Edits, Oh My!

If you’ve ever pondered a hyphen situation, inserting and deleting that pesky hyphen to see “what looks right,” you’re not alone. Incorrectly hyphenating is one of the most common proofreading (proof reading?) and copy editing (copyediting?) errors we writers make.

One might say it’s a lifelong problem.

Or is it life-long? Life long?

Our best answer—as with many word-related challenges we face—is the dictionary. At Allegory Editing, we use Merriam-Webster, though there are other options out there. No matter what dictionary you use, consistency is key. Still, it’s good to be on the lookout (not look-out, according to Merriam-Webster) for compound words. At times we might breeze past them, so add this to your list of proofreading (yes, it’s one word, not two) tasks.

It’s important to know the three basic options for compound words. Sometimes they are one word (the adjective lifelong); other times they’re two words (the noun copy editor); and we also see hyphenated words (the adjective off-limits).

I recently came upon a questionable compound word and asked a couple of Allegory Editing team members what they thought. We decided we weren’t sure about Merriam-Webster’s answer:

The author complained of a stomachache, so her agent suggested a weeklong vacation to Hawaii.

The author complained of a stomach ache, so her agent suggested a week-long vacation to Hawaii.

The one-word version of stomachache is correct, according to the dictionary. We thought it looked funny. After some further digging, we discovered both ways are considered acceptable. At that point, we made the choice that felt right for the material. Hyphens can be a tough call because the reason for hyphenating most compound words is, in fact, ease of reading.

By the way, the dictionary also says weeklong is correct.

What’s your gut feeling about the word stomachache?
