The semantic diffusion is defined as non determining of the content of linguistic signs (the morphemes, words, word groups, sentences, texts), the indistinct character of borders between semantic categories in the system of language as well as in the linguistic communication. Semantic diffusion is a multiaspectual phenomenon, characteristic both for language, as and for parole. In the first part of article the author discusses the semantic diffusion in system of language, and namely in range of the derivation affixes, and also in range of the referential and signification meaning of the words.
