Hopefully People Will Stop Complaining about “Hopefully”

Some people can’t get over the word “hopefully.”

They want it to only mean, “in a hopeful manner,” and not to mean, “I am hopeful that”.

Thus, the following paragraph from here:

—
Everyone uses “hopefully” as a shortcut for “I hope.” It is not. Yes, the dictionary allows it, but that’s just bending to popular usage. In my book, there is only one correct use for “hopefully.” It’s a synonym for “prayerfully”—as in, “She looked up hopefully and said, ‘Dear Lord, please make it rain soon, or we’ll have no harvest.'” Do you want to say “I hope”? Then say “I hope.”

The dictionary bends to popular usage. Well, most English-speakers use the word that way, so I guess the dictionary really should bend by now.

And guess what, the dictionary has a way to include a word, while saying that it’s nonstandard. In this case, the dictionary “allows it,” by saying that it’s the common usage.

I wonder whether we’re allowed to say, “thankfully” to mean, “I am thankful that,” or if it has to mean, “in a thankful manner.”

Do we have to say, “I was wonderful when I watched the movie.” Full of wonder?
