Low German

I still don't know the full extent to which Andalusada's butterflies change the evolution (and survival) of languages. I do know that Mozarabic survives, or at least evolves into a spoken language the world recognizes as "Moorish."

At least one other language survives to Andalusada's present day: Low German, in various iterations.

Pommersch

To the extent that Low German has a standard, it would be Pomeranian. This was the dialect standardized in the Günther Bible, which subsequently became the chancery language of Pomerania.

• Refugees and escapees from the Reductions created a trans-Atlantic Pomeranian diaspora, which stretched to at least Moorish Mexico. The descendants of this diaspora have made it a co-official language of Hispano-Baltic Texas, and several lines of the House of Sansinger (mostly those descended from Kaspar) speak it to the present day.
• Since the Treaty of Meissen re-established Pomerania, Pommersch has gone from being the chancery language to the official one.

Pommersch also survives as something of a Güntherite Yiddish.

Other dialects of Low German

"Pommerish" isn't the only dialect of Low German spoken in the world, merely the best-defined. Others include, but aren't limited to:

• Lübsch. The Low German of Lübeck, which eventually standardized in response to the Günther Bible. [details?] Pomeranian may be the dominant dialect of the Baltic now, but Lübsch has had more influence within the Low Countries. [details?]
• "Platt." French has patois, dialects-or-maybe-languages that are only recognized regionally. Because of the more scattered German language families, any German dialect spoken only overseas can be simply called "Platt" without any further specification.
