Compound Adjectives before Nouns
If punctuation is a guide to help your reader
understand more quickly and easily, then hyphens can be very useful
signposts. One of the most important and
overlooked functions of the hyphen is to warn the reader, "Hey, I'm a
compound adjective!" Unfamiliar
with the terminology? It doesn't
matter. Your readers' brains are
familiar with the reality.
Take this classic example:
Hyphens, just like commas, can decide who lives and who
dies.
Hyphens in Compound Adjectives
A compound adjective is two words that function as one
word to modify a noun. In
"man-eating alligator," man and
eating work together as one
unit. It's not a man alligator and an
eating alligator. It's a man-eating
alligator.
Rule: If a
compound adjective comes before a noun, you can (and often should) hyphenate
it.
A thin-bladed
knife
A 30-mile race
A
nervous-looking boy
A leather-bound
book
Bird-like legs
A well-known
politician
Exception : If the compound adjective uses an
adverb ending in –ly, don't hyphenate. This is because the –ly already alerts
the reader that this will be a compound adjective.
A badly cooked
steak
A wildly painted
car
A quickly
written memo
Note: Some
people prefer to leave out the hyphen if the meaning is clear without, but that
can be dangerous. The meaning is obvious
to you, since you wrote it. The reader doesn't
have the same advantage. So be careful
if you decide to omit these hyphens. And
always be on the lookout for situations where the lack of hyphen can completely
change the meaning, as in the examples below.
Hyphens Clear up Ambiguity
From Grammar
Monkeys:
Small-state
senator (a senator from a small state)
Small state
senator (a state senator who is short and thin)
A violent
weather conference (a weather conference where people punch each other a
lot)
A
violent-weather conference (where meteorologists professionally discuss
violent weather)
A hot yoga
teacher (an attractive yoga teacher)
A hot-yoga
teacher (one who teaches yoga in a purposely hot environment, as in the
style of Bikram yoga)

(a great resource)
I have a few
more important things to do. (A few more tasks remain on my list of
important things to do)
I have a few
more-important things to do. (I can't do what you suggest because I have
tasks that are more important.)
He returned the
stolen vehicle report. (At first, most of us will think he returned the
vehicle he stole. Then we come to
"report" and we're confused.)
He returned the
stolen-vehicle report. (Here it's clear that what he's returning is a
report about a stolen vehicle. The
vehicle is probably still missing.)
From Apastyle.org
Students who
live in two parent homes (students who split their time between two homes
where parents also live)
Students who
live in two-parent homes (students who live in a home with both parents)
From Wikipedia:
Zero-liability
protection (you are not responsible in any way if something bad happens)
Zero liability
protection (you have no zero protection if something bad happens)
Examples I've come across lately in reading:
Hard sell
tactics (selling tactics which are difficult to perform)
Hard-sell
tactics (aggressive selling tactics which perhaps play on the fears of the
potential buyer)
A long deserted
chamber (a long—perhaps narrow—chamber that happens to be deserted at the
moment)
A long-deserted
chamber (a chamber that has been deserted for a long time)
Hyphens Make Reading Smoother
Here are some other examples that aren't so ambiguous
but that will still often trip up the reader for a moment if you leave out the
hyphen. Making your reader stop to think
and re-read is something you should reserve for clever plot twists, elegant and
thought-provoking lines, or intriguing ideas.
Don't make them stop and re-read because of lacking punctuation.
Steel-plated boots
Custom-made device
Death-dealing steel
Decent-sized vessel
Grey-haired man
Sword-shaped hole
North-facing terrace
Cream-colored stones
Dirt-eating scum
Fire-lit faces
Remember that if you want to wrap your reader in your
characters' world, you need to provide as few pointless distractions as
possible. And unclear punctuation is one
of the biggest culprits in the world of pointless distraction.
