Dialects
The linguistic varieties of Extremadura are usually classified in three main branches: Northern or "High" (artu estremeñu), Central or "Middle" (meyu estremeñu), and Southern or "Low" (baju estremeñu). The northern one is usually considered to be the language proper, and is spoken in the north-west of the autonomous region of Extremadura, and the south-west of Salamanca, a province of the autonomous region of Castile and León. The central and southern ones are spoken in the rest of Extremadura, and are not different enough from standard Spanish to be considered anything but dialects of it, since at least the 18th century.
Northern Extremaduran is also spoken in a few villages of southern Salamanca, being known there as the "palra d'El Rebollal", which is now almost extinct.
