The everyday language spoken by ordinary people in a particular region or country, as opposed to formal, literary, or scholarly language. Vernacular represents authentic, natural speech patterns and local expressions.
From Latin 'vernaculus' meaning 'domestic' or 'native,' from 'verna' (home-born slave). The term originally distinguished local languages from Latin in medieval Europe, later expanding to describe any informal, native speech versus formal registers.
Vernacular was revolutionary in literature—when Dante wrote 'The Divine Comedy' in Italian instead of Latin, he democratized poetry! Similarly, the King James Bible's use of English vernacular made religious texts accessible to common people, fundamentally changing both literature and society.
