This paper compares the proportions of different word classes present in 30 Italian
children at two specific stages of vocabulary development (200 and 500 words). The
Italian version of the MacArthur Communicative Development Inventory and spontaneous
speech samples produced during an observation session were both used to examine the
extent to which these children produce quantitatively different vocabulary
compositions. Both methods revealed a greater presence of nouns than other word
classes in the sample studied, although significant differences were found in the
noun/other word class proportions.
