This article deals with a metaphor in critical communication situations. The critical communication situation is defined here as such condition when the available and ready-made linguistic means within the standard inventory are not felt to be adequate to express the intentions of the speaker. The cognitive value of poetic metaphor can not be judged in isolation from its communicative function. Art is no a distortion of reality in the pejorative sense but rather a distortion of conventionality. The need to talk of thinks in a new way is experienced not only by poets. Linguistic creativity is allowed in everyday speech that is incessantly in reached with new expressions.
