Abstract
To understand the cultural connotation of phrase logical units, it is necessary to interpret the figurative basis of the internal form of phrase logical units in the sign "space" of the Uzbek and Russian languages community. This is the main thing in the study of cultural and national specifics of phrase logical units. Cultural knowledge is "caught" from the internal form of phraseology because it contains such elements that give the phraseology a national-cultural flavor. Uzbek phrase logical units, reflecting elements of culture, are associated with many areas of human life. At the same time, they can be connected both with the everyday and empirical experience of the people, and with the sphere of material culture, with the historical experience of the people, etc.
