Abstract: The systemic and stratificational realization of Grammatical Metaphor embodies a intrinsic metaredundancy which gives rise to the meta-redundant metaphorical effect at lexicogrammatical stratum where meaning potential of one type of Grammatical Metaphor extends simultaneously to planes of other types of Grammatical Metaphor and redounds with metaphorical Theme and Metaphorical News. The essence of Textual Metaphor is rooted in the meta-redundant effect of Grammatical Metaphor which enables its intrinsic metaphorical realization and leads to the redundancy of Textual Metaphor for limiting its operation at lexicogrammatical stratum.
