AP style refresher 2
I had to look this up yesterday, in the hyphens entry in the punctuation section:
Many combinations that are hyphenated before a noun are not hyphenated when they occur after a noun: The team scored in the first quarter. The dress, a bluish green, was attractive on her. She works full time. His attitude suggested that he knew it all.This came up in a discussion of a sentence like "Compared with Bob, he is less-understood." The hyphen looked awkward to me, but it certainly follows that AP rule.
But when a modifier that would be hyphenated before a noun occurs instead after a form of the verb to be, the hyphen usually must be retained to avoid confusion: The man is well-known. The woman is quick-witted. The children are soft-spoken. The play is second-rate.
