Is the word for "fifth" spelled correctly?
I have noticed that, in the "Numbers" classes, the word for "fifth" is written as "पाँचवा". But I remembered reading, and just checked, R. S. McGregor's books on Hindi ("Outline of Hindi Grammar" and "The Oxford Hindi-English Dictionary"), as well as H. H. van Olphen's "First-Year Hindi Course", and they both spell it "पाँचवाँ", with the chandrabindu on the last syllable. Still, Hindi is not my first language, so can anyone verify if it is really misspelled here in Duolingo? This is important, as the "-वाँ" suffix is used to form all ordinals above seven.
