If your professional life requires adherence to AMA style, you may have gotten lost in the weeds styling hyphenated compounds in titles. No capitalization after a hyphen if a prefix or a suffix, if both parts are considered a single word (requiring a field trip to Merriam-Webster), if the compound is temporary, or if the parts do not carry equal weight.

I have long wondered how parts of a compound carry weight, which isn’t to say that I don’t like the idea. As a practical suggestion, though, it lacks a little, uh, practicality.

If you think of a compound as an entity on its own, any word that may carry weight because of its particular part of speech loses that identity (and drops the weight!) when it gets pulled into that magical realm of a hyphenated compound (all adjectives all the time). So “Short-term Effects” and “Full-time Coverage” have always read as weird to me, especially if they have appeared near “Early-Onset Disease.”

How fitting, then, that the AMA Manual of Style has finally addressed the weed problem with hyphenation. No need to kill them. We can just get them out of our way. Let the weeds live happy lives in some other organization’s style manual.

The new guidance in 10.2.2 reads “In titles, subtitles, and text headings, capitalize both parts of a hyphenated compound.” Hence, “Short-Term Effects” and “Full-Time Coverage.” Take a look in the online manual for more information and other new style guidance.

Now when you review capitalization in titles with hyphenated compounds to align with AMA style, you needn’t make excursions to other sources. You can stay in the AMA garden without getting lost in the weeds.
