摘要：Mothers of 58 20-month-olds in Seoul,the Republic of Korea,completed vocabulary checklists for their children. When vocabulary level was taken into account,children`s vocabularies contained relatively greater proportions of nouns than other word classes,and more verbs than adjectives or closed-class words. Correlations among word classes showed that each word class was consistently positively correlated with every other class. Girls` vocabularies were found. Factors that influence vocabulary size and can account for gender and individual differences are discussed. Noun prevalence in the vocabularies of children learning to speak Korean,and the merits of several theories that may account for this word-class prevalence pattern,are evaluated..
