One of the characteristics of standard Italian is the retention of the -"re" infinitive ending, as in Latin "mittere" "send". Such infinitival ending is lost in Tuscan as well as Corsican, which has "mette" / "metta", "to put". The Latin relative pronouns "qui"/"quae" "who", and "quod" "what", are inflected in Latin; whereas the relative pronoun in Italian for "who" is "chi" and "what" is "che"/"(che) cosa", it is an uninflected "chì" in Corsican. Perhaps the biggest difference between standard Italian and Corsican is that the latter uses the "u" termination, whereas standard Italian uses the "o" ending. For example, the Italian demonstrative pronouns "questo" "this" and "quello" "that" become in Corsican "questu" or "quistu" and "quellu" or "quiddu". This feature was typical of the early Italian texts during the Middle Ages.
