Which one of the languages below is an example of 'vernacular'?
Latin
Italian
Summarian
Greek
Italian would be considered a 'vernacular' language in this context.
Vernacular refers to the everyday, common language spoken by the general population of a particular region or country, as opposed to a more formal, literary, or prestigious language.
Latin, Greek, and Summarian are not considered vernacular languages. Latin was the dominant literary and scholarly language in medieval Europe, while Greek and Summarian were ancient classical languages.
Italian, on the other hand, developed as the everyday spoken language of the Italian people, distinct from the more formal and literary Latin that was used in official and scholarly contexts. Italian is therefore an example of a vernacular language.
