Although sincerity is universally valued, its linguistic expression and cultural framing vary significantly across speech communities. This article examines the parallel concepts of sincerity in English and samimiylik in Uzbek, focusing on their semantic structures, pragmatic realisation and culturally embedded norms. Drawing on a corpus of 270 naturally occurring dialogues from British and Uzbek television talk-shows, advice programmes and informal YouTube vlogs, the study combines corpus-driven semantic analysis with ethnographically informed discourse interpretation. The findings show that while both cultures align sincerity with truthfulness and emotional transparency, English discourse tends to foreground individual authenticity and mitigate overt affect through politeness strategies, whereas Uzbek discourse embeds sincerity in relational warmth, solidarity and culturally salient metaphors of the heart. These differences affect how praise, criticism and disagreement are performed. The article argues that a nuanced awareness of such divergences can enhance intercultural communication and guide pedagogical practice in English-Uzbek translation and language teaching.
