Resum: La crítica ha trobat al Curial e Güelfa petges molt evidents d’influència de la literatura italiana, i en particular de Boccaccio. Tanmateix no ha estat estudiada una altra influència italiana, la purament lingu?ística. Un estudi detingut del Curial ha permés identificar a l’obra nombrosos elements que mostren la seua origen italiana. Molts d’aquests elements es troben presents a les obres de Boccaccio, concretament en el Decameron. Per cada element identificat al Curial s’ofereixen exemples de les obres de Boccaccio.Paraules clau: Curial e Güelfa; Boccaccio; italianismes; influència; catalàAbstract: Several scholars have found in Curial e Güelfa very clear traces of influence of Italian literature, and in particular of Boccaccio. Therefore, no other Italian influence, the purely linguistic one, has not been studied. A detailed study of the Curial has identified many elements that show their italian origin. Many of these elements are present in the works of Boccaccio, specifically in the Decameron. For each item identified in Curial, we provide some examples from the works of Boccaccio.Keywords: Curial e Güelfa; Boccaccio; italianisms; influence; Catalan
