whats the difference between dinner and supper?

I think it just depends on where you live and what your family says. In our house we had breakfast, lunch, ans supper. If you said dinner it was in reference to something more special like sunday dinner. Or you had company over to dinner not supper. I fid myself using dinner more for our evening meal than supper as I grow older...

Dinner refers to the heaviest meal of the day while supper means the evening meal. In some areas, lunch is dinner since it is their biggest meal. For others, dinner is supper.

All the different names for meals is very confuding, here in Australia dinner can also called tea that is the evening meal but then dinner can also be thought of as lunch the afternoon meal, I remember telling a friend I would be at her place for dinner about 3 pm O get a phone call asking why I didn't show up, dinner to my friend was lunch where dinner for me is the evening meal...supper would be after dinner.... :)

I guess I eat dinner, not supper. I don't like to eat really late. I might eat dinner at 5 and have a snack around 7.

maybe "dinner" is commonly used by Englishmen, while "supper" is the word for Americans.. hehe.. dunno..
