In this article, new anisotropic grand Lorentz spaces are defined and their propertөies are studied. These spaces are a new structure that provides a unified parameter for the study of various functional spaces. The consideration of grand spaces is especially important for the study of boundary conditions of parameters and allows us to achieve new results in this area. The study of boundary parameters in classical spaces is not always possible. In recent years, grand Lebesgue spaces and their generalizations have been widely studied in problems of functional spaces. These spaces are generalizations of classical Lorentz and grand Lorentz spaces. The article defines grand anisotropic Lorentz spaces, gives basic estimates in these spaces, proves embedding theorems, and derives embedding theorems for parameters. The results obtained can play an important role not only in theoretical, but also in applied problems.
