stören : to disturb => zerstören : to destroy
"Ver-" is not quite so bad as "Zer-", but is rarely good.
schlafen : to sleep => verschlafen : to sleep for too long
"Er-" is worse than "Ver-", and debatably as bad as "Zer-", for it ends in certain death.
schiessen : to shoot => erschiessen : to shoot dead
I once got confused between being stung by a wasp: "Ich wurde von einer Wespe gestochen." and being stabbed to death by a wasp: "Ich wurde von einer Wespe erstochen."
Today I made another prefix mistake. I was trying to say "I furnished my room" and ended up claiming "I executed my room". One letter, one prefix, and a rather different meaning.
