This thesis aims to analyze the linguistic and pragmatic deployment of perlocutionary acts in diplomatic speech by exploring Uzbek and English discourse texts. It endeavors to discover how and in what linguistic and pragmatic ways perlocutionary effects are encoded, spread, and construed within institutional communication practices in general. From a comparative perspective, the study scrutinizes the effect on language/cultural norms of the perlocutionary influence. It demonstrates that these practices of perlocution are established by lexical, grammatical, and discourse practices of politeness norms, indirectness, and communication intentions. This research advances the theoretical study of linguopragmatic language and also presents tangible implications for intercultural and diplomatic communication.
