Languages of Spain - Naming Convention

As part of the coverage The Guardian is providing for the new linguistic measure in the Spanish Senate, a graphic artist from the reporting website has created an interactive map showing the areas where the different Spanish languages are spoken. It's very simplistic, but it should give the average reader an idea of the language situation in Spain.

The creator of the map, Mark McCormick, apparently got his sources mixed up. It seems that, on the left side, his intention was to have the language name in English, followed by the name in the language it mentions. This is correct for some of the languages we see here, though certainly not all. For instance, on the correct side, Spanish has the label castellano in parenthesis, and next to Catalan, we find català; Basque has a correct euskara. Galician, however, is not Gallegu in Galician, but galego; gallegu is the name for this language in Asturian. Extremaduran has its translation rendered, not in Extremaduran, but in Aragonese. The same is true for Astur-Leonese, which has its name written in Aragonese. In the case of Aranese, it goes a step further, with its short description in Aragonese (variant d'o gascón).

Below is a chart illustrating the correct names for these languages in the same language referenced by the name.

Spanish	castellano (español)
Catalan	català
Basque	euskara
Galician	galego
Fala	fala
Astur-Leonese	asturianollionés
Extremaduran	estremeñu
Aragonese	aragonés
Aranese, dialect of Occitan	aranés, dialècte der occitan

[UPDATE 1/20/11: The map now displays correctly the Galician > galego part; the other incorrect labels continue as such.]
