Hi everyone! I know that when a compound is used as an attributive adjective before a noun, it needs to be hyphenated. The professor is a well-dressed man. We hold this time-honored tradition dear. The world-class athlete won the gold medal. Generally speaking, when a compound is used predicatively (after the verb), the compound isn't hyphenated. The professor is well dressed. Does this also apply to permanent compounds that are hyphenated in the dictionary? Merriam-Webster’s hyphenates both “time-honored” and “world-class” and lists them as adjectives. Does this mean that regardless of the manner in which they are used (attributively or predicatively), compound adjectives such as “time-honored” and “world-class” should always be hyphenated? This tradition is time-honored. or This tradition is time honored. The athlete is world-class. or The athlete is world class. I’ve found divergent opinions on the matter, and I would love to settle this once and for all! For instance, the <<Chicago Manual of Style (CMOS)>> states that “when [compound modifiers] follow the noun they modify, hyphenation is usually unnecessary, even for adjectival compounds that are hyphenated in Webster’s (such as well-read or ill-humored).” However, the Merriam-Webster Learner’s Dictionary offers this as an example of the use of the adjective “time-consuming”: “Can we try to make this less time-consuming?” Your help is, as usual, greatly appreciated!
