hyphens, compound modifiers
As a general rule, compound modifiers are hyphenated before the noun but not after the noun: "The team scored in the first quarter." "The team scored a first-quarter goal." However, when a modifier that would be hyphenated before a noun comes after a form of the verb "to be," the hyphen is usually retained: "The scholar is well-known." "The child was soft-spoken." Two words that are commonly associated do not require a hyphen: the real estate agent, the health care system. Compounds that end in "ly" are not hyphenated: the newly appointed dean, the nationally ranked hockey team.
