Q. Is this a true phrasal adjective, in which case it should be hyphenated as shown, or should it not be hyphenated? “We offer innovative and technologically-advanced solutions.” There is a difference of opinions.
A. Although this is a phrasal adjective (an adjective, advanced, that is modified by an adverb, technologically), Chicago style does not hyphenate compound modifiers formed with adverbs ending in -ly. Please see CMOS 7.91 and 7.93.
