Bashkir, a distinctive language belonging to the Kipchak group of the Turkic language family, has some archaic elements in terms of its semantics, vocabulary, and word formation compared to other Turkic languages. Many Old Turkic lexemes still survive in Bashkir, preserving their archaic meanings. Almost a quarter of the vocabulary of Old Turkic consists of hapaxes. This article will compare the Old Turkic hapaxes and the Bashkir vocabulary. The results of the study show that 32 Old Turkic hapaxes still exist in Bashkir. The Old Turkic hapaxes that will be dealt with here are bagirlan-, bicis-, burcaklan-, burgalan-, arsaklan-, atla-, itla-, isigla-, kadisla-, karlan-, kactur-, kidigla-, kutan-, kuglan- I, kuza-, orum, talagu, tarmaklan-, tartislig, tayis-, tamurluk, tisat-, tuplan-, tuplat-, tusluk, uklus-, yazlat-, yemsin-, yersin-, yetizlik, yigim, yiglis-, and yuncit-. The paper is organized as follows: Brief information is given about the term hapax and Bashkir in Section 1, Introduction. In Section 2, a total of 32 hapaxes are discussed.
