So my understanding is that you can use "hangi" if the houses are not able to be referred to as the first, second, third, etc house. Can this sentence be used interchangeably, structurally speaking? "Fil hangi evde"?
yes, if you are not asking for the number. for "hangi" you would expect an answer like this house, that house, the rad house etc
"Fil kaçıncı evde?"
Translation: Which house is the elephant in?
In which house is the elephant?
Correct other English answer accepted by Duo.
does (kaçıncı) means which??
Kaçıncı means: "ordindal which". One could say: the "howmanieth".
Why do not use "Hangi"?
I thought "hangisi"? Why "kacinin"?
In which house is the elephant in? Marked wrong. ??? Why?
