Hyphens matter. Because thirty-odd proofreaders are not the same as thirty odd proofreaders.
Or perhaps they are. But I digress.
If you’re having trouble deciding if you should use a hyphen, check the would-be phrase in your favourite dictionary. I’m always amazed how many are listed. In fact, would-be can be found in the Macquarie Dictionary.
If the phrase can’t be located, there’s a simple rule to follow. Generally, you should hyphenate two or more words acting as a single thought (called a phrasal adjective) that come before the noun they are modifying.
For example, consider the difference between thirty-odd proofreaders and thirty odd proofreaders. The first means there are somewhat more proofreaders than the indicated thirty. The second indicates the thirty proofreaders are peculiar in a freakish or eccentric way. Which we usually are, but again I digress.
Clarity is the name of the game. If your intended meaning is unclear to your readers, definitely add a hyphen. Thirty odd proofreaders will thank you!
