It keeps coming up. It's an company wide problem. It's causing industry-wide confusion. I fear it might be a nationwide dilemma.
My research leads me to prefer the unhyphenated one-word version, but I can't find an objective external source to help my colleagues out. Often a single document contains two or more versions of this admittedly overused construction.
Can you help?
-Glenn
Glenn, for spontaneous or nonce constructions, it should be hyphenated.
company-wide
industry-wide
economy-wide
However, there are some -wide constructions that are well established which are written as one word:
nationwide
countrywide
citywide
There are no forms of this that should be written as two words without the hyphen.
I have noticed also that when referring to mobile homes it appears to be hyphenated as well(single-wide, double-wide, triple-wide, etc.)
