THE WORD “JANUBIO”
Janubio is a place-name that designates an area of the south west of the island of Lanzarote and, within it, other secondary accidents, such as a beach, an internal lagoon separated from the beach with a strip of land, and salt flats that are there implanted since ancient times.
Perhaps it is these salinas that have given the most notoriety to the name of Janubio, but that does not justify in any way that they explain their etymology, as proposed by Sosa Barroso (2001: 154): Janubio – says – comes from Sal Nuveo «Cloudy, cloudy salt», which evolved to jal nuveo and from there to janubio. On the contrary, the place name seems of Guanche origin, but nobody, without even Wölfel (1996: V, 53), has not been able to give an explanation from the point of view of its meaning.
As for writing, currently only one way. Janubio, but not so in previous times. The first time it is recorded is on the Torriani map, in 1590, and it is done as Anuvio, and the same in the Brihuela / Cosala cartography, in 1635; and the same, but with b, in P.A. del Castillo, in 1686. Only from Riviere (1741) and Viera (1772) is it fixed in the way it has arrived until today. Other forms, such as Berthelot’s Xanubio, are pure individual solutions.
