Lexically similar verses of the Holy Qur’an constitute a field in which, at first glance, verbal repetition may be assumed; however, careful attention to their formal variations reveals diverse semantic layers. The present study aims to examine and elucidate the semantic differences of lexically similar verses in Surah al-Baqarah. Employing a descriptive–analytical method and drawing on the principles of cognitive semantics, such as context-dependence of meaning, perspective, focus of attention, trajector, and landmark, the study analyzes cases of omission and addition in lexically similar verses of Surah al-Baqarah in comparison with other surahs. The findings indicate that numerous verses in Surah al-Baqarah exhibit lexical similarity with verses in other surahs, with their differences primarily manifested in the omission or inclusion of specific nouns, verbs, particles, or clauses. Examination of these variations shows that, although the verses appear to convey a single theme, they in fact represent two or more distinct conceptualizations of a shared reality. The results further demonstrate that omission and addition in lexically similar verses are directly related to semantic restriction or expansion; verses containing added elements typically display broader semantic scope and encompass a wider range of referents.
