[nq:1]Is there any semantic (or any other) difference between the expressions 'have a look' and 'take a look'?[/nq] I don't think so. It may be a simplistic assumption, but I think the former is British and the latter American. I may be wrong. They're pretty much a matter of preference now, though.
