Name created in 1998 by Emily Quelch in New Zealand, for her daughter, word was taken from greek word for goddess Thea and made into a name which sounds like "Tiana" but pronounced Tay-ah-na to differentiate it from the name which comes from "follower of christ"; tiana. Thea was also a name given to the moon sometimes by Greek people and it can mean "shining".
A man of Greek origin. May own small islands in the Aegean and welcome visitors with exuberant declarations of 'Welcome to my island'. Thanasis is generous, fun-loving, romantic, sexy, a great lover and a true and loyal friend. Thanasis will lend you anything and try to procure anything you want that he doesn't have. Often quite hairy. Likes to party hard, love well and uses the word brave to mean big. A Thansis is a wonderful human being.
