There is breakfast, and of course; breakfast for dinner. But on Sunday’s, there is breakfast for lunch, or what the ‘cool kids’ call “brunch”.
Wikipedia: A meal is not usually considered brunch if it is started before 10:30 am; such meals would still be considered breakfast. Typically brunch is had between 10:30 am and 2 pm, close to lunch time but still before. Brunch is usually eaten in the late morning.
Oh, and enjoy!
