A comprehensive survey on the etymology of three Avestan words

Some Avestan words have been more of a subject for discussion and debate among scholars of Avestan texts; every scholar has interpreted and analyzed the words and the texts based on their own evidence. Although many of Avestan words have clear and specific roots, there still exist some which have gained significance through etymological and analytical research conducted on them due to disagreements among linguists. The current study is a survey on three such words: (1) Pairika (Pairik?-), (2) Khnathaiti (Xn??aiti-) and (3) Gandarewa (Ga?dar?Ba-). These are the names of mythological creatures of the younger Avestan texts. This study is a precise examination of the etymology and source of these words.
