in a hopeful manner, it is hoped ; I hope ; we hope ,
Usage: In the 1960s the second sense of hopefully, which dates to the early 18th century and had been in fairly widespread use since at least the 1930s, underwent a surge in popularity. A surge of criticism followed in reaction, but the criticism took no account of the grammar of adverb s. Hopefully in its second sense is a member of a class of adverb s known as disjuncts. Disjuncts serve as a means by which the author or speaker can comment directly to the reader or hearer usually on the content of the sentence to which they are attached. Many other adverb s (as interestingly, frankly, clearly, luckily, unfortunately) are similarly used; most are so ordinary as to excite no comment or interest whatsoever. The second sense of hopefully is entirely standard.
