Why hyphens (or lack of them) mean your true blue friend is a Smurf and you should not fear free dentistry. We have lots of examples that will help you finally understand hyphen rules.
Most authorities also point out exceptions. They say that some compounds need a hyphen even when they follow the noun. Which compounds, though … razor-sharp? risk-averse? time-sensitive? all-encompassing? cost-effective? blue-green? Authorities disagree. Some defer to dictionaries, but you can’t necessarily go by a dictionary. As The Chicago Manual of Style says, “When such compounds follow the noun they modify, hyphenation is usually unnecessary, even for adjectival compounds that are hyphenated in Webster’s (such as well-read or ill-humored).” (4)
Crazy-making! As John Benbow, once editor of the Oxford University Press stylebook, is widely quoted as warning, “If you take hyphens seriously, you will surely go mad.” (5)
So much for seeking the right answer.
Happily, we’re seeking not a right answer but a right question. Most authorities don’t tell you that if you wonder, Do I need a hyphen here? after the modified noun, you ask the wrong question. They don’t tell you what you most need to know: that a post-noun modifier almost always follows a be-verb (is, are, was) or some other linking verb (seem, appear, become, remain, grow, get). And they don’t tell you that linking verbs almost always signal an opportunity to strengthen a sentence.
So what question should you ask yourself when faced, heaven forbid, with sentences like these?
- This job is long term.
- That child is razor-sharp.
- The suit is blue-green (or blue green).
Ask yourself, What do I have to say about that long-term job, that razor-sharp child, that blue-green suit? Then, eliminate the linking verb, and swap in some substance, some muscle:
- This long-term job pays more than anyone in Joan’s family has ever made.
- Those razor-sharp kids speak twelve languages.
- Donovan thought that the blue-green suit made the professor look glamorous.
In all those examples, the compound adjective is hyphenated because it comes before the noun. And now, you have yourself sentences worth reading.
1 This hyphenless headline, which splashed across the back cover of the New York Times Magazine on November 27, 2011, also suffers from a noun-pronoun mismatch. Grammatically, the they refers to the would-be subject, bond, as if to say, “The bond are joined at the liver.” Ouch again. Not the best way for a hospital to advertise its attention to detail.
