I thought negated sentences didn't require a hai on the end.
They don't, but it is good practice to use them whenever an 'is/are' or 'isn't/aren't' is being used.
I'm confused as to when nahi is supposed to be after or before a modified word.
Me too. I don't understand why मेरी दादी आ रही नहीं हैं was marked incorrect. Does anyone else know why?
नहीं usually comes before the verb- in this case "आ रही हैं" is all part of the verb so नहीं has to come before all of it
Maybe dadi is still sat on the road #bandh
