This study sought to determine if a child’s inventory of denominal verbs (e.g., swing as a verb) at 42 and 54 months are predicted by their inventory of related nouns (e.g., swing as a noun) at 30 months and whether these relationships are different for late talking and typically developing children. Keywords consisting of denominal verbs and related nouns were extracted from 42 late talking and 44 typically developing children at 30, 42, and 54 months. Preliminary results revealed that related noun inventories at 30 months predict denominal verb inventories at 42 months. However, related noun inventories at 30 months do not predict denominal verb inventories at 54 months. These results suggest that differences in noun inventories are linked to denominal verb inventories regardless of language status, but only in an early window of development.
