- A good example of the unpredictable and often capricious nature of usage controversies is the current issue of hopefully as a sentence adverb.
- A conjunctive adverb frequently functions as a sentence adverb, but it also has a "joining" (conjunctive) quality that points back toward the preceding clause or sentence.
- For decades now self-appointed grammar mavens have railed against the use of hopefully as a sentence adverb.
The traditional definition of an adverb is that it is a word that modifies the meaning of a verb, an adjective, or another adverb, as in, for example, he shook his head sadly. However, another important function of some adverbs is to comment on a whole sentence, either expressing the speaker’s attitude or classifying the discourse. For example, in sadly, he is rather overbearing, sadly does not mean that he is overbearing in a sad manner: it expresses the speaker’s attitude to what is being stated. Traditionalists take the view that the use of sentence adverbs is inherently suspect and that they should always be paraphrased, e.g. using such wording as it is sad that he is rather overbearing. A particular objection is raised to the sentence adverbs hopefully and thankfully, since they cannot even be paraphrased in the usual way (see hopefully (usage) and thankfully). Nevertheless, there is overwhelming evidence that such usages are well established and widely accepted in everyday speech and writing.
