I always get confused because I'm sure an entree should be a starter.
I think it depends where you are in the UK sometimes to how you phrase things. I live right in the middle of the country and here we call the meal in the evening teatime. However if I was going out for a posh meal it wouldn't be tea and I wouldn't say dinner either as dinner is whet I have at midday.
Could the term ginger come from the colour of a ginger tabby cat? I have no idea on this one sorry.
