Matlab jaisay if u see in urud we have seperate pronouns and if u say tum or tu it sounds rude but aap is specific for addressing respectfully.Not really. We use(d) Che(h) for 'You'. Many use Aap now though not of Koshur origin.
So koshur has these seperate pronouns or has one like you in english and in english as its just one so its nothing rude etc, tell me?
