Hazar, Melis ÖykuŞimşek, Yılmaz2024-03-132024-03-132023-02-212687-4814https://hdl.handle.net/11693/114641The aim of this paper is to investigate and survey some fundamental functions, which are related to homomorphisms, properties that can be used to change active voice into passive voice. These functions are explained with the relevant examples. Some observations are also made about how the inverses of these functions can behave. Finally, we raise a number of new and distinct problems that allow for further research and analysis to fully comprehend grammatical structures. © 2023, MTJPAM Turkey.
