I was reading an "article" on the BBC website and stumbled over this:
"Has the game been successful so far?
"Hasn't it just!"
I say stumbled because this strikes me as very BE, and I was unfamiliar with it. So I did some looking.
It is definition #14 in the Oxford Learner's Dictionary entry for "just":
used to agree with somebody
‘He's very pompous.’ ‘Isn't he just?’
Oxford doesn't mark this particular use of "just" as BE, but it strikes me as such and is marked that way in Cambridge Learner's Dictionary: isn't it/aren't they just?
informal used to strongly agree with what someone has said about someone or something: "This is very expensive." "Isn't it just?"
It's almost #6 in the AHD entry, but in AE you can't use just by itself, as you can in the BE idiom.
1. Precisely; exactly: just enough salt.
2. Only a moment ago: He just arrived.
3. By a narrow margin; barely: just missed being hit; just caught the bus before it pulled away.
4. At a little distance: just down the road.
5. Merely; only: just a scratch.
6. Simply; certainly: It's just beautiful!
7. Perhaps; possibly: I just may go.
I found two relevant threads in the forum:
Looking at the German definitions for "just" in LEO, this meaning seems to be missing. It's quite colloquial, though, and I wouldn't want to rely on my sprachgefühl for the German side. Does this merit a new entry? If so, I will need help on the German side. Also, searching for examples for the English is difficult because I get a lot of hits on sentences with a following adjective, as in "Isn't he just amazing?"
