@bobsal u1553115,
Supper is more of a Northern thing, down South 8t's Dinner.
It would only be supper if it was particularly late, say if you'd had dinner about 6 or 7 then had a long night and had something substantial before going to bed.
Then there's tea and high tea, as well as elevensies thrown into the mix.
When I was in America and we talked about meals they thought we had all of them which would be about eight or nine meals a day, which would be really bloody going some.
