Abstract
This article presents an expanded comparative investigation of the temporal deictic lexemes today in English and bugun in Uzbek on the basis of corpus linguistics, lexical semantics, syntactic distribution, and frame semantics. Although both lexemes are conventionally translated as indicators of the current day, corpus evidence demonstrates that they are not functionally symmetrical. The English lexeme today reveals broad categorial mobility, semantic polysemy, and discourse-pragmatic extension, particularly in newspaper language where it frequently encodes informational freshness, public immediacy, and socio-historical contemporaneity. The Uzbek lexeme bugun, while sharing the core temporal meaning, exhibits stronger narrative anchoring, event-localization, emotional urgency, and dialogic dramatization in literary discourse.
