Usage Discussion of IMPORTANT

A number of commentators have objected to importantly as a sentence modifier (sense 2) 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>.
