frukost - breakfast in Swedish frokost - breakfast in Norwegian frokost - lunch in Danish
I since looked it up and apparently it comes from early food not seed.
From Middle Low German vrōkost ("early meal"), from vrō ("early") and kost ("meal, food").
In Germany, earlier or still formally "Frühkost" has been/is used for breakfast. Particularly in hospitals or health facilities, this archaic term is used today.
Since I am German, I am confused with all these English, Swedisch and Danish "meal expressions". So, when exactly is the time to eat "frokost" in Denmark? Is it similar to the German "Mittagessen"?
it depends on the time people stand up in the morning. May be Danish upperclass stood up at noon time. They had then a first frokost : their early meal . Workers, peasant had a much earlier meal = morgenmad. Bon appétit!
