I often heard people say: "Es ist mir klar...." so the answer I gave here was: "Ist es Ihnen klar, dass Sie zwei verschiedene Schuhe tragen?" Is that incorrect?
I would leave out the "es", because the thing, which is "klar" or not, is mentioned in the subordinate clause.
Danke für die Erklärung!
bitteschön :)
Does any body know why are they using "ist" and not "sind"?
Literally "Ist Ihnen klar,..." would be "Is (it) clear to you,..."
Ahhh! danke!
I think there is an implied subject here. You could leave the sub-clause and change the sentence to: "Ist es (Ihnen) klar?"
Yes, the sub-clause is the subject, which the "es" would replace.
Could you say "Erkennen Sie . . . "?
That sounds philosophical. You wouldn't say that.
Thank you. I'll keep that in mind.
