The article is devoted to the creative world of V. Zhilka as a “possible world” in the context of Belarusian poetry dated 1920s–1930s of the 20th century. National poetry of that period is distinguished by a constellation of talented authors, unique poetical themes, and inheritance of artistic traditions. Vladimir Ivanovich Zhilka (1900–1933) was a Belarusian poet and translator. His verses are focused on the following subjects: love of homeland, unique and ancient Belarus, emotional and expressive spirit of a creative person, imperfect manifestation of a sign, beauty as a notion and beauty of the surrounding world, music, etc. These themes are also vividly expressed in the rhymes of A. Alexandrovich, Z. Astapenko, M. Bagun, V. Dubovka, A. Dudar, and other authors. Key poetical concepts of V. Zhilka and the above-mentioned poets are: motherland, melancholy, nature, and beauty. It should be noted that in V. Zhilka’s verses the concept of native land is correlated with the concepts of music and sorrow; the melancholy concept has a much greater realization extent than the concept of joy; the concept of nature is very philosophic; converging concepts of beauty and nature are based on the ability of a creative personality to explicate emotionally all aspects of the inner ego. In his “possible world” all cited concepts are often realized with the semantic component “incomplete expression of a sign, partial manifestation of phenomenon.”
