The article examines the typology of taboo vocabulary in Russian

and Uzbek linguocultures through ethnographic descriptions of

rituals, everyday practices, and family-life scenarios. Based on

lexicographic sources, ethnographic records, and contemporary

media texts, it identifies the central thematic domains of tabooing and

the cultural codes that underlie them. Particular attention is given to

euphemisation strategies, including metaphorical and metonymic

renamings, periphrastic constructions, borrowings, and clipped

forms that enable indirect reference while preserving culturally

salient meanings. The study demonstrates that the selection of a

euphemism is shaped not only by the degree of prohibitedness of the

referent but also by communicative intention, discourse type, and the

addresseeʼs expectations. The proposed model, correlating categories

of taboo vocabulary with corresponding types of euphemistic

substitution, offers a more precise account of the dynamics of value

orientations and the shifting boundaries of the permissible in Russian

and Uzbek linguocultures, and provides implications for

lexicography, corpus annotation, and the teaching of intercultural

communication.
