sentence adverb the sentiments of the speaker. "Unfortunately", however, is only one of many sentence adverbs that can modify a speaker's attitude. Others include "mercifully," "gratefully," "oddly," "admittedly," etc. Hopefully "Hopefully" is an example of a word whose use as a disjunct ("it is hoped") is sometimes controversial. (Most / More) importantly This commonly used sentence adverbial phrase has been decried by some grammarians. Examples of its use, from the OED, are: 1941 Jrnl. Royal Aeronaut. Soc. 45 309 Just as importantly, the chart is of extreme value in forming any decisions as to the desirability of modifying‥the track. 1962 H. R. Williamson Day Shakespeare Died viii. 88 More importantly, Shakespeare, though using Holinshed as his main source, occasionally used Hall as the direct source of various passages. 1969 Nature 1 Nov. 477/1 Most importantly, when the particles of the pair are brought together, they annihilate. Writers have claimed that the preferable phrase should be "more (or most) important". For instance, Washington State University English professor Paul Brians writes:When speakers are trying to impress audiences with their rhetoric, they often seem to feel that the extra syllable in “importantly” lends weight to their remarks: “and more importantly, I have an abiding love for the American people.” However, these pompous speakers are wrong. It is rarely correct to use this form of the phrase because it is seldom adverbial in intention. Say “more important” instead. The same applies to “most importantly”; it should be “most important.” However, Merriam-Webster write:American commentators seem to object to the adverb and recommend the adjective. and, after discussion, conclude You can then use either the adjective or the adverb; both are defensible grammatically and both are in respectable use.
