Nel asturianu de les zones central y occidental esisten dos expresiones asociaes a la negación, non y nun, que tienen consideráose tradicionalmente variantes d’una mesma unidá llingüística. Sicasí, les diferencies na so distribución sintáctica (Martins 2010, 2014) y nel so valor pragmáticu-discursivu (Ducrot 1972, Horn 1989), xustifiquen la esistencia de dos unidaes negatives distintes. La aplicación de les pruebes de Horn (1989) y Martins (2010, 2014) muestren que nun ye un marcador de negación interna, oracional o regular que tien efeutos na estructura interna de la oración, mientres que non ye un marcador de negación metallingüística periféricu, esternu a la estructura oracional, que s’emplega pa refugar una aseveración previa. L’estatus de marcador periféricu atribuyíu a non permite amenorgar los distintos tipos de combinaciones y secuencies aparentemente heteroxénees a una estructura sintáctica básica na que la disposición de los constituyentes ta bien rellacionada colos procesos de topicalización y focalización que provoca non.
There are two words in Central and Western Asturian, non and nun, that have traditionally been considered variants of the same linguistic item. However, the differences in their syntactic distribution (Martins 2010, 2014) and their pragmatic and discursive value (Ducrot 1972, Horn 1989) prove the existence of two different negative items. The application of the tests proposed by Horn (1989) and Martins (2010, 2014) bring to light that nun is an internal negative marker (also called sentential or regular negation) that affects the internal structure of the sentence, meanwhile non is a peripheral metalinguistic negative marker, external to the sentential structure, which is used to refute a previous utterance. The status of peripheral marker attributed to non allows us to reduce the number of combinations and sequences, apparently heterogeneous to a basic syntactic structure in which the arrangement of the constituents is closely related to the processes of topicalization and focalization caused by the word non .
