A megametaphoric event is an experiential gestalt embodying both propositional and metaphoric actions.

In megametaphoric metafunctions, the syndromes produced by its ideational function in syntagmaxis form the basis of signifying chains,with its registral elements co-occuring and extending regularly in the same text so as to form the extensive and gestalt semantic framework of a metaphorical text;meanwhile,the metaphoric degrees can be shown in the rankshifts produced in parataxis.

The complete theory of textual megametaphor contains semantic metaphor and syntactic metaphor.
