Simarly byls jste was rejected. Can someone explain when you use Byls etc with and without jste or jsi to mean you.
Byl(a)s is a shortening of byl(a) jsi.
Thanks for the quick response. The mystery is solved for me.
why can't you use "byl jsi"?
I wrote : Ty jsi byl dobrý manžel, why is that wrong?
Where's the "very"?
