The paper aims to defend classical numerical monism against thesis about predicative monism (Barnes, Curd). The instrumentarium is rich in philological-philosophical argumentation. The main line is the thesis of Mourelatos about Greek words on genos, genes suffixes and the argumentation of C.H. Kahn from The thesis on Parmenides. Argumentation is also against localistic interpretation of sphericity of Being in Parmenides.
