Is there an adverb in English that can be used to refer to the number of people who do an action? For example we say
Henry, Frank and Alex pulled the heavy box together.
Is there a structure like an adverb to put here as in
They pulled the heavy box [...]
An adveb which probably means in a group of three or something like that.
We have this type of adverb in our native language so I was wondering if it does exist in English, too. I have never seen it though.
It is supposed to be a kind of contrastive analysis!
