To those who don't use "tea" - What would you call a light evening meal? If you had a cooked meal at lunch/early afternoon, then something light in the evening. Would it be supper, or something else?
Northerner (now living in London)
Was breakfast, lunch and dinner in my household
Tea was what we had as small children as our early evening meal when we ate earlier than my parents - once we were old enough to wait till my dad got home, we had dinner
Tea was then just a snack (sandwich or similar) when we got in from school, to keep us going till dinner time when we would eat as a family
Same down south with my friends' kids. If they're fed their evening meal at nursery of the childminder around 5pm, before pickup, it's tea. Once they're old enough to eat with the family, that evening meal is dinner
So I think of tea as a timing thing tbh. If I had a very light meal very early evening (say 5 ish) then I suppose I might call that tea - because it's too early for dinner. If I'd had a main meal at lunch, then if I wasn't going to have a proper evening meal, but had something light to eat, I'd probably call it a snack / light dinner if it was normal dinner time (any time after 7pm). Tea is early evening, not the full evening meal.
In an employment contract the time in the middle of the day is usually referred to as a lunch break, rather than a dinner break
Restaurants have lunch and dinner menus.
