Varietas (linguistica)
Varietas in sociolinguistica, etiam lectos appellata, est ulla linguae gregisve linguarum forma, quae linguas, dialectos, registra, stilos, et alia linguae genera, adeo cum varietate normativa, comprehendere potest. Usus vocabuli varietatis ad varias formas attingendas vocabula evitat linguam, quod multi homines exemplar normativum putant, et dialectum (saepe cum varietatibus non normativis), cui minus auctoritatis aut probitatis saepe attribuitur. Linguistae varietates normativas et non normativas investigant.
