El problema de la hipotètica diftongació en català en el context de les altres llengües romàniques

Abstract

The present article shows how the traditional theory on the closing of the short and stress E and O in Catalan to i/i, postulated among others by Joan Coromines and Joseph Gulsoy, is unconvincing, due to the fact that neither the applied conditioned diphtongisation is the same as in the rest of the Romance languages, nor have they occurred in the same time as in the Occitan, as the orthography demonstrates. Thus, the author, more naturally, postulates a double closing E>e>i/O>o>u.
