Hello : Nomoskaar Goodbye : Bidai
"Dhanyabad." <---Not bengali "Dhon-no-bad"
You can say "உங்கள் கோபத்தில் உள்ளேன்" (Ungal kopathil ullen) to express that you are mad in Tamil.
First of all, I don't understand the question, but I will try to answer it the best I could. To say mad, all you have to do is say MAD. M-A-D, MAD. Easy!
