You should let it out of the oven.
Why the first word is "iss" instead of "yaga"?
As far as I understand, the को modifies the noun phrase to an oblique case.
Because "This" = "Iss"
what does को mean in this sentence?
To her/it, By it/her, (or like the other person put it "onto" her/it) = The hotness is being felt onto/by/to the cat, therefore "This cat is feeling hot" "Ko" basically means "she/it IS" as "Usko bhookh lagi hai" = "She is" hungry.
Ko means as, on, to.....
So i see, the Duolingo is trying to flirt with me huh?? ;) ;)
That was the one on the hot tin roof.
