Dîvânu Lugâti't-Türk (DLT) is a Turkish-Arabic bilingual translation dictionary based on the vocabulary of the 11th century Turkish language. The purpose of translation is to provide equivalence between the two languages. It is very difficult to provide equivalence in translation. The fact that Arabic and Turkish are quite different both linguistically and culturally caused some equivalence problems and loss of meaning in the transfer of some grammatical categories to Arabic in DLT. In Karakhanid Turkish, there is no one-to-one "grammatical equivalent" in Arabic for the -(I)ş- morpheme. This situation caused the grammatical functions of the -(I)ş- morpheme, which marks different event types in Turkish, to be lost and the functions of the target language to be copied incorrectly. This made it difficult to determine the functions of the -(I)ş- morpheme and caused it to be transferred incorrectly. In the secondary translations of the DLT (Arabic-Turkey Turkish), it is seen that since the original text and language are not used, the loss of meaning is multiplied, it causes the transfer of grammatical categories in Arabic, let alone ensuring grammatical equivalence, and the misdescription of the functions of the -(I)ş- morpheme. In this study, the loss of meaning and equivalence problem experienced in the translation of the functions of the -(I)ş- morpheme in DLT and its translations are emphasized. It has been argued that the grammatical equivalence of the -(I)ş- morpheme in DLT and its translations cannot be achieved and is subject to various losses. Considering that linguistic origin and cultural partnership facilitates equivalence, it has been suggested that grammatical equivalence can be determined by "intralingual translation" from Karakhanid Turkish to Turkey Turkish, and some grammatical functions of the -(I)ş- morpheme were determined with morpho-syntactic approaches.
