The traditional taboos of mankind are the taboos of the sacred and of the impure. The issues of language impoliteness, verbal aggression and taboo violence have only recently come under a more intensive scientific scrutiny. The paper offers some possibilities for successfully avoiding of taboo words, wherefore it can also be a contribution for a better understanding of taboos in our own, as well as in other cultures and languages. However, the existence of differences between the languages was not sufficient to predict target-deviant behaviour. The question whether language dominance determines cross-linguistic influence has been discussed controversially in studies on simultaneously bilingual students. Flouting taboos entails direct or indirect, social or cultural sanctions.
