A perda da série reducida feminina do posesivo en textos notariais galegos e portugueses da época medieval: cronoloxía e pautas no proceso de difusión da innovación / The loss of the reduced feminine possessive series in Galician and Portuguese notarial texts from the Middle Ages : chronology and course of the process of innovation spread / La perte de la série réduite féminine du possessif dans des textes notariaux galiciens et portugais de l'époque médiévale: chronologie et normes dans le processus de diffusion de l'innovation

In this approach we try to show the differences between medieval notarial Galician and Portuguese texts during the process of decay and later the abandonment of the reduced feminine series ma, ta and sa of the possessive. By means of a model composed of three phases: a first one of taking advantage of the opposition between reductions and complete forms according to criteria of functional character, a second one of transition and a final one of extinction of the syntagmatical viability of the reductions, it is observed that the linguistic varieties to the North of the Mino differ from those to the South not only in the chronology of the phase's change but also in the relative duration of each of them. Finally we examine the problem of convergence and divergence between the notarial register and the oral use by elaborating a typology of occurrences of reduction organized in a scale according to their representativity as evidence for the survival of the series on the edge of the written use.
