Barranquenho

Barranquenho (Barranquenhu) is a Romance linguistic variety spoken in the Portuguese town of Barrancos, near the Spanish border. It is a mixed language, and can be considered either a variety of Portuguese (Alentejan Portuguese) heavily influenced by the Spanish dialects of neighbouring areas in Spain in Extremadura and Andalusia (especially those from Encinasola and Rosal de la Frontera), or a Spanish dialect (Extremaduran / Andalusian) heavily influenced by Portuguese.

Barranquenho speakers maintain that they speak neither Spanish nor Portuguese but a third language altogether different. Ethnologue lists Barranquenho (as Barranquian) as a dialect of Extremaduran, perhaps because Barrancos was populated by settlers from Badajoz, a city in Extremadura, though not in an Extremaduran language speaking area.

The development of Barranquenho seems to be relatively recent, the variety developing no earlier than 1527 and likely by the early 1800s, unlike other minority linguistic varieties in the Iberian Peninsula, which have medieval roots.
