Dear abigbull in Bengali Da or Dada means bhai or bhaisahab in Hindi or SIR in eng .
Dear Biswa
Pls respect his sentiments he does not like to be referred as (_______ da ) added as a suffix , and time and again Ghosh has clarified it .. so take it into consideration ..
But if the junta is hell bent on adding " da " as a suffix then i think even Mr .Ghosh can't do much abt it .
