Abstract
This article explores the historical and theoretical perspectives on proper nouns, focusing on their role and significance within language and linguistics. From the Renaissance and Middle Ages, scholars such as T. Hobbes, J. Locke, and G. Leibniz examined the lexical importance of proper nouns, with G. Leibniz advancing T. Hobbes's theory of "embodiment" by linking proper nouns to elements of both abstract and concrete thought. This approach laid the foundation for abstract-logical and concrete-historical methodologies in linguistics. This article also explores the crucial role of anthroponyms in linguistics, highlighting their significance across various linguistic domains.
