importantly vs. important
A number of commentators have objected to importantly meaning “it is important that” as a sentence modifier and have recommended important instead. Actually both the adverb and the adjective are in reputable standard use in this function. Important is always used with more or most <had bronze weapons and composite bows; more important, they utilized the horse and war chariot — Harry A. Gailey, Jr.> <second and most important, the book contains no important woman character — F. Scott Fitzgerald>. Importantly is somewhat more flexible in not requiring more or most <sticks and, just as importantly, unsticks easily — Phoebe Hawkins> <importantly, the leaven in the mixture is quality — George O'Brien>.
