The recording clearly didn't say "keiner"...
Possibly because it precedes a word starting with an "a" sound?
Can a native speaker confirm?
Shouldn't "none work" be an accepted answer? Or is that a different German word?
Sorry, I only know 'no one works' and I know 'no work'. It would be helpful to describe your 'none work' a bit. Then German natives could get out what you want to say by 'none work'.
So is Keiner the default word with no adjective changes?
How is arbeitet pronounced? sounds like albeitet to me..... something about rolling the R really heavy or what?
