How to understand みんなしてお出かけですか?


I have seen some cases where して is placed before a する verb:

> 1) みんなしてお出かけですか？
>
> 2) みんなして大好評だな

Is this regular practice? Is this grammatically correct? Can this be done with
other conjugations of する?




What you're seeing is not お出かけする written in a strange order, but a fixed
adverbial phrase **みんなして** ("get together and (do ～)", "with many others",
一緒になって, 集まって). 大好評 is not a suru-verb in the first place. みんなして doesn't have
to be followed by another suru-verb. For example みんなして同じ事を言う means everyone
says the same thing almost at the same time (=口を揃えて言う).

You cannot use みんな as a regular suru-verb. みんなして [is a fixed expression
derived from archaic
Japanese](https://japanese.stackexchange.com/q/42718/5010), and it always
appears exactly in this form. In archaic Japanese, して was used like a
standalone particle similar to で in modern Japanese. See
[this](http://www.hello-school.net/haroajapa010011.htm) and
[this](http://people.ucalgary.ca/~xyang/kobun/6-2-11.htm). 三人して meant 三人で,
血して書く meant 血で書く/血を使って書く. You may still see this type of して in literary
sentences. みんなして doesn't sound particularly archaic to me.

二人して is also used in modern casual conversations (e.g., ねえ、二人して何やってるの？).
