This article analyzes the formation and development of knowledge from the perspective of semiotic systematization. Knowledge is interpreted as a process through which information about the external world is transformed into a symbolic-cognitive construct by means of sensation, perception, experience, logical generalization, and social agreement. The article examines the emergence of signs, symbols, sounds, words, texts, and concepts, as well as the mechanisms by which they are transformed into knowledge, on the basis of naturalistic, conventional, anthropological, and cognitive approaches. It also distinguishes genetic, artificial, and social forms of knowledge and explains their role in human thought, experience, cultural relations, and the system of formal education.

Onomatopoeic words in Japanese constitute an independent lexical-semantic system consisting of five groups. One of the most fundamental features of onomatopoeic words in Japanese is the regular, systematic connection between phonetic form and meaning. This article examines the lexico-semantic structural features of onomatopoeic lexicon in Japanese, focusing on the categories of giongo (擬音語) and gitaigo (擬態語), analyzing their classification, phonosemantic isomorphism, and grammatical usage through concrete examples. The article demonstrates that Japanese possesses a uniquely developed onomatopoeic system compared to other world languages.
