Abstract
The article deals with the problems of idioms production and perception related to the foresign forms emergence of information accumulation and storage contained in the cognitive-based derivation of phraseme building. It is suggested that presign stage of the semiosis process and the phraseme understanding is a cognitive model that precedes not only the formation of the phraseme semantic structure, but its perception. Since the cognitive model of phrasemic semiosis is a diagram of discursive meaning embodiment and discourse itself is form of its indirectly derivative existence, there is a need to show how the cognitive-discursive mechanisms of phraseme building is associated with foresign forms of sense accumulation and storage.
