Harry Ritchie, in English Grammar for the Natives (2013), writes that hopefully is “by far the most controversial adverbs of recent times” (p. 191). Usage of the adverb, he says, “has been met with fierce resistance”, and he quotes from Kingsley Amis’s usage guide, which reads that “when someone says or writes, ‘Hopefully, the plan will be in operation by the end of the year,’ we know immediately that we are dealing with a dimwit at best” (1998: 158).
Ritchie says that there are signs “that the resistance is nearly over”. Perhaps it is, but we can’t test it with the help of our regular usage surveys because the feature is not included in the study by Mittins et al. (perhaps because it wasn’t as yet as widespread as the others they deal with). So here is a separate usage poll, on hopefully only: please tell us what you think.
