When the first modifier in a compound is an adverb ending in "-ly" (e.g., "a poorly written novel"), various style guides advise no hyphen. However, some do allow for this use. For example, "The Economist Style Guide" advises: "Adverbs do not need to be linked to participles or adjectives by hyphens in simple constructions... Less common adverbs, including all those that end "-ly", are less likely to need hyphens." In the 19th century, it was common to hyphenate adverb–adjective modifiers with the adverb ending in "-ly" (e.g., "a craftily-constructed chair"). However, this has become rare. For example, "wholly owned subsidiary" and "quickly moving vehicle" are unambiguous, because the adverbs clearly modify the adjectives: "quickly" cannot modify "vehicle".
