Due to its archaic elements, Chuvash language is one of the most studied dialects among contemporary Turkic languages. However, even though the studies on the Turkish tribes have increased in Turkey since 1990s, it is difficult to say that Chuvashes have benefited thoroughly from that interest. Even though the terminology existing in the other Turkic language accents have been referred to in many studies especially on folk literature, it has been observed that not many terms of Chuvash folk literature have been mentioned. In this context, terminology of Chuvash folk literature, which contains the archaic elements in terms of language, religion and folklore, may conserve these archaic features. Therefore, this article discusses the naming of the genres and forms through narrowing this subject within folk literature. The terms are respectively discussed without mentioning the forms and genre discussions of the researches of folk literature. The terms studied are generally the ones which are accepted and rooted in public in oral culture as well as scientific researches. The terms like yuri, yumah, halap which are common and -to an extent- complicated will be examined in more detail. Those terms are examined simultaneously and diachronically, and the origins and the spread of these terms in other Turkish tribes is tried to be determined though a comparative study. Such terms as myth, legenda, epos etc., which have been used in the studies of Chuvash folk literature have been excluded from this article. In addition, many other terms apart from the namings of genres and forms have also been excluded from this study.
