Hyphens, En Dashes, Em Dashes
Q. Where does Chicago stand on this “eco” compound word madness? Everything that comes across my desk these days is “eco-conscious, ecobusiness, eco centered,” and of course not a single word of it is consistent.
A. Chicago style closes up most prefixes, following Merriam-Webster, but if you’d rather hyphenate, set your own style and record it in your style sheet.
