The /ʎ/-/ʝ/ merger (yeísmo) in central spain: advances since the ALPI

This paper studies the advance of the /ʎ/-/ʝ/ merger (yeísmo) from the 1930s in territories linguistically considered transitional between northern and southern Castilian, in rural speeches from the center of the Iberian Peninsula. Its starting point is the Atlas Lingüístico de la Península Ibérica (ALPI) maps, and the paper published on them by Tomás Navarro Tomás, comparing them to those from the Atlas Lingüístico y etnográfico de Castilla-La Mancha (ALeCMan) and from the Atlas Dialectal de Madrid (ADiM). Our results allow us to confirm the unstoppable progress of the /ʎ/-/ʝ/ merger and the geographical direction of the change.
