Componential analysis of the dictionary definitions of anthroponyms has revealed that two layers of object-logical content of the word are realized in their meaning - denotational and significative. The presence and prevalence of either of these two components in the semantic structure of anthroponyms determine their sign status. As a result of generalization of their semantics we single out the following main semiological classes: 1)anthroponyms proper, 2)real, 3) relative, 4)nominal, 5)collective, 6)deictic and 7)quantifier anthroponyms.
