Dont write crap if you dont know the history. Telugu in Andhra and as well in Telangana region was same and best of the poets actually came from Telangana. Various language related works and experiments (like avadhanam etc) was very well practised in Telangana. It was only in 14th/15th century onwards due to Nizam's evil rule the language was influenced by Urdu (due to forceful implementation of Urdu). It has become fashion to comment Telangana people by their accent. Please stop this, you can variation in language accent across andhra, compare nellore with vizag accent. We speak telugu and there is no difference among people of andhra pradesh.
