Euphemisms are vital elements of language, especially in polite speech training, tracing language change and use. Hence, the lack of studies on the distribution of euphemisms in Swahili denied stakeholders knowledge of what Swahili speakers consider sensitive and less sensitive. In this regard, the current study determined the distribution of Swahili euphemisms by taboo themes. The data were collected from 384 Swahili speakers using a questionnaire. The euphemisms were categorised by taboo themes, whereas the ranking was based on the volume of euphemisms per theme. The finding reveals that the theme of “dead body” had the highest concentration of taboo phrases, followed by themes of “burial” and “farting." The least euphemised themes in Swahili are “female sexual organ," "semen," and “orgasm." The hierarchy implies that speakers should trade carefully on topics of dead body, burial, and farting in Swahili communication. Contrarily, relaxation is permitted in conversations around sexual organs, semen and orgasm in the Swahili culture. The findings might be useful to native people who are upbringing their children according to the Swahili culture, diplomats and orienters of foreigners in the Swahili culture.
