in a null-subject language such as italian, however, pronominal subjects are not required (in fact, in many null-subject languages, producing overt subjects is a sign of non-nativity). these type of "unstressed" pronouns are called clitic pronouns. therefore, italian uses a different inflectional morphology on verbs that is based on the person features of the nominal subject it agrees with:- camminare ("to walk"):cammino ("i walk)", camminiamo ("we walk")cammini ("you walk"), camminate ("you all walk")cammina ("he/she walks"), camminano ("they walk")
