"Δεν υπάρχει απόδειξη για αυτό."

[JuliaPrespa]

Can you also translate Δεν υπάρχει απόδειξη για αυτό as 'there is not a receipt for this'?

If it's just been added, great, if not then for some reason it's not working as this answer wasn't accepted (it was a strengthening exercise).

"there is no proof for this" is currently marked as incorrect, general strengthening on web. I'd say that "of" and "for" are fairly interchangeable in this context in the English.

[spdl79]

Thank you!

[SvenSchlin]

"There is no proof for that" is not accepted but sounds better to me than "of". Is there a reason for that?

[Plakakaneis]

"Is"still not accepted

"There is not a receipt" was not accepted but i think it should be

[MiltiadisA1]

my answer: There is no proof about it. I believe that my answer is correct

[G.Georgopoulos]

It's either "proof of" or "proof for".
