अनुवाद:वे बिल्लियों की अनुमति नहीं देते हैं।
My long standing contention which I have stated a few times earlier also is that in present imperfective negative sentences the ending हैं/है/हूँ/हो should not been used.
But there is no response on it from Duolingo Hindi team till date!
Apparently I too have many doubts and queries... May be the Hindi team is much more busy in preparing for the upcoming ENG-HIN course... Btw, Vinaybhai, your answers do a lot of help to my queries.. So, as far as I concern, I simply do NOT care if the Hindi team looks at my comments or not, I still have my doubts solved. Thanks to the active members like you.. :)
