Extremaduran is a Romance language, spoken by several thousand people in Spain, in an area covering the northwestern part of the autonomous community of Extremadura and adjoining areas in the province of Salamanca. It should not be confused with the Spanish dialects spoken in most of Extremadura, though it is difficult to fix the boundary between both languages.
The pronouns and verbal conjugation are more likely Castilian, presenting some forms common to Leonese.
