Lacunar and real units as transmitters of ethnocultural asymmetry in creative discourse were examined typologically. Content analysis, interpretive, and comparative methods were used to explore the semantic structure and cultural character of units in texts from diverse national traditions. Kyrgyz, Turkish, Chinese, and French literature formed the empirical basis. Kyrgyz literature shows that realities and lacunae fix stable ethnocultural self-awareness incorporated within the text’s axiological and ritual structure, encompassing collective identity, holy rites, and moral orientations. The concepts of el (people, community), aiköl (generous, magnanimous), and bata (blessing) were conceptually and pragmatically untranslatable because they included cultural and historical connotations, ritual functions, and specific social norms. The main causes of gaps in Turkish literature are social organization, tribal affiliation, and ethical/behavioral norms (ağa, aşiret, namus), which reflect culturally conditioned disparities in interaction patterns and role expectations. Chinese literature shows mental, physical, and ceremonial lacunae induced by cultural taboos, social hierarchy, and distinctive physical representation. French literature has demonstrated cognitive and sensory forms of lacunae associated with the absence of moral causality, the autonomy of the subject, and the individualised perception of sensory experience. The investigation revealed four categories of untranslatability: lexical, conceptual, pragmatic, and sensory, each reflecting deep ethnocultural incomparability. The study found that lacunae and realities produce interpretative tension and semantic fragmentation by indicating cultural codes, behaviour patterns, and symbolic systems. The research clarifies cultural otherness analysis mechanisms and develops ethnoculturally marked text interpretation methods for translation studies, intercultural communication, and literary analysis.
