@oristarA,
Quote:Can an activity be "set up"?
Yes, of course it can. To set-up something, to set something up, means to establish it.
Some of the problems you are encounering are caused by the tendency of some modern authors to use looser language than necessary.
Then of course, in those cases, A2K contributors can help.
I would have thought however, that "to set up a venture" should have been easy meat for a chap like you with a dictionary.
I advise use of the dictionary (it must be a good E-E dictionary) because in reading round the target word or phrase, you learn a lot more.
