Reduplicated babbling is replaced by variegated babbling, producing syllable structures such as C1VC2V (e.g. "cane" 'dog', "topo" 'mouse'). Production of trisyllabic words begins (e.g. "pecora" 'sheep', "matita" 'pencil'). Consonant clusters are now present (e.g. "bimba" 'female child', "venti" 'twenty'). Ambient language plays an increasingly significant role as children begin to solidify early syllable structure. Syllable combinations that are infrequent in the Italian lexicon, such as velar-labial sequences (e.g. "capra" 'goat' or "gamba" 'leg') are infrequently produced correctly by children, and are often subject to consonant harmony.
