The research focuses on forming tolerance in profession-oriented text translators as part of the process of developing their sociocultural competence. To this end, the author analyzes the notion of " tolerance” in Russian, German and English linguistic culture and the specifics of profession-oriented text translators’ work. Based on a survey of professional translators, the concept of " profession-oriented text translators’ tolerance” is considered a personal professional quality (in this case, related to geologists). The author justifies its importance and proposes a model for forming translators’ tolerance at four stages of developing the sociocultural competence of profession-oriented text translators. This professionally important quality will help translators successfully carry out cross-cultural communication in their professional sphere. © 2019, Slovenska Vzdelavacia Obstaravacia.
