The waitress gave them pizza mistakingly / mistakenly

[reginaregina]

Could I use the following sentence to describe a situation which the waitress gave customers pizza but actually they ordered something else? Thank you.

The waitress gave them pizza mistakingly.

"mistakenly." Otherwise, it's perfectly understandable. For me, the word order is better as:

"The waitress mistakenly gave them pizza."

It isn't wrong the other way but I think it is clearer if "mistakenly" is close to "gave" since it is modifying "gave".

You could also say "the waitress gave them pizza by mistake".

"By mistake" sounds less formal than "mistakenly"

As JamesM said... mistakenly gave them pizza.

Or you could say, gave them pizza by mistake.

I see a dearth of usage of "mistakingly", so much so that I'd actually ask if it was a word prior to using it myself.
