I had a German exchange student in my class and he always used "schlagen" in a weird way and it was hard to understand him. I know "schlagen" means "to fight" in English but what does it mean in German slang?
I'm going to mention all different usages of this verb I found in dictionary.
Herz, Puls to beat (heftig) to pound
(auxiliary 'sein' or 'haben')(= auftreffen) mit dem Kopf auf/gegen
Regen to beat
(auxiliary 'sein' or 'haben')
Yiddish has quite a few meanings depending on the prefix.
derschlagen sich zu... means to reach your destination with some effort.
derschlagen as an adjective means depressed or dejected.
vorschlagen (as in German) means to suggest or propose.
ausschlagen can mean to cover as in "to cover your expenses". It can also mean to knock out.
unterschlagen means to line a garment.
uberschlagen means to throw a cover on top of.
abschlagen means to repel or reflect; also, to dissuade. In the reflexive (with sich) it can mean to bounce off. An Abschalg can be a repercussion.
beschlagen can mean to upholster, to cover, or to break out in (a rash).
