Why not "On yedi kediler var" ? why not "On yedi kediler vardır" ? why not "On yedi kedi vardır" ?
Why not kediler:
Because we already know there are several cats (seventeen). You do not need the -ler ending when the amount is stated.
Why not vardır:
Because the -dir ending is for unchanging facts. For example: The earth has a moon.
It's almost always singular after numbers, it's a rule
Yeah why not "kediler"? Why is it in singular here?
Why "Orada on yedi kedi var" is incorrect ?
That would be "There are seventeen cats there" :) There is no need for "orada" in this sentence.
"There are seventeen cats."
Translation: On yedi kedi var.
"On yedi tane kedi var." Duo accepted this answer.
I inserted "tane" after "seventeen" or "On yedi."
