Non-stability of semantic complex of poetic text's units in light of theory of intertextuality

The system of poetic text is examined from textual and linguosynergetic positions. The theory of intertextuality is described. The brief typology of intertextual relations is given: hyper-, in-, para- and architextuality. The basic systemic linguosynergetic signs of the poetic text are determined: openness, instability, nonlinearity. The sign of instability is analyzed in detail from the standpoint of the intertextual nature of the units of the poetic text. The poems by J. Keats “Nebuchadnezzar’s dream” and T. York “Airbag” are used as practical material.
