Abstract The article is about describing appeals to agitation (concern, worry, excitement, and bother) as a type of emotive speech acts found in scientific dialogue that contains features of both scientific and everyday speech, which makes the inter-discourse interrelation possible within dialogical forms of scientific communication. This interrelation helps the markers of everyday speech (including appeals to agitation) get into scientific dialogue making the latter more expressive and emotive in comparison with the other genres of scientific discourse (an article, monograph, review, dissertation, presentation, etc.).
