The starting point of the article is the claim that poetry is a linguistic expression of subjective relationship to some selected events. Reading a poetical work, a receiver finds something that is self-governed and that is more or less unique entity. This uniqueness, however, is heavily restricted by the linguistic medium of poetry. After all, the sender achieves the individual expression by the most individual realization of the most typical elements of language. Concrete poetry, as the author sees it, is an attempt to break the aforementioned rule: it does not aim at a mere individual set of types, but more at a unique pattern of concrete realizations, i.e. the vehicles of word. It is in this way that a word receives clarity of color and sound. The clarity in question could be closely connected with the meaning of the poem, strengthen it with its picture, or considerably weaken the representing character of speech.
