This article examines the theoretical foundations of sociolinguistics and its significance in international diplomatic communication. It explores the interrelation between language, social structures, cultural identity, and power. The study also analyzes code-switching, multilingualism, the relationship between language and gender, and the role of English in global diplomacy from a sociolinguistic perspective. The article argues that language should be understood as a central construct shaping and reflecting social realities, rather than a neutral or autonomous system.
