Nadal, on the other hand, has been interested in the history of Catalan language but always in relation to other historical processes that European languages have undergone, especially Romance languages.Moreover, they have worried about theoretical and methodological aspects, so that led them to discuss questions linked to the concept of language itself and the role played by disciplines such as philology and linguistics in the history of languages.These questions have focused several international colloquia held in Girona with the motto "Problems and Methods of History of Language" that, throughout more than twenty years, have gathered internationally recognized researchers like , Bernard Cerquiglini, Sylvain Auroux, , John E. Joseph, , , Maria Leonor Carvalhão-Buescu, Paolo Trovato, Jean-Michel Eloy, Rosanna Sornicola, etc.
