The aim of the article is to show the semantic aspects of grammar modeling while applying the cognitive linguistic approach. The authors analize the correlation of universality of the Complex Object model and its specific features in speech. The referent embodiment is realized through its mental activity (perception, assessment, causation, and willingness). Analyzing the Complex Object structures in communication the authors come to the conclusion that blending is realized with the help of spatial and temporal markers: the process of subject causative effect and the object predicted result; the process of sensory perception and the (un)real picture of the developing event. Duration in time or moving in space to completeness processes are represented in the standard grammatical model and vary due to verbalization of thought in speech.
