The purpose of the research is to study linguopoetic heritage of A. Potebnja as a theoretical basis of linguocreatorics of XXI century. We state that problems of language activity and activity in language have to be solved in the modern linguocreative format. A. Potebnja has formulated the basic ideas of theoretical poetics as it appears in the ХХ and XXI century. The researcher has proved that by studying poetic language linguists can explore the language resource, patterns and directions of the creative realization of the national language. Potebnya pointed to the continuous changes in the language. The scientist managed to investigate which linguistic facts were remnants of the past, which belonged to the present, and what only occurred and its development would only depend on language activity that meets the needs of human thought. These points form the basis for the modern development of philology as linguocreatorics, linguistic and literary modeling. Poets as linguocreative persons realize language activity connected with linguocorrection.
