"Tana" is a Pnar word which means "handkerchief". Nowadays it is not used by everyone. It is the older generation who used it and it is mainly confined to jowai, Meghalaya. The Pnar word that is now commonly used for handkerchief is "rumar". "Rumar" in Pnar and "rumal" in Khasi are borrowed words from the Hindi language.
