In what situations would the use of a colloquialism be deemed inappropriate in formal spoken Russian?

Using colloquialisms, which are informal words or phrases used in everyday conversation, would be inappropriate in formal spoken Russian in situations demanding respect, professionalism, and adherence to established norms. These situations include official presentations, academic lectures, legal proceedings, business negotiations with high-level executives, and formal interactions with government officials. In these contexts, the use of colloquialisms can undermine the speaker's credibility and convey a lack of seriousness or respect for the audience and the situation. For instance, addressing a judge in court using slang would be highly disrespectful and could have legal repercussions. Similarly, using colloquial language during a formal presentation at an academic conference would detract from the seriousness of the research being presented and could be perceived as unprofessional. In formal business negotiations, particularly with older or more traditional Russian partners, colloquialisms can create a negative impression and hinder the development of trust. The expectation in these settings is to use standard literary Russian, demonstrating command of the language and respect for the established hierarchy and protocols. Therefore, adhering to formal language conventions is crucial in situations where maintaining a professional and respectful image is paramount.
