Language can be classified as expressive and receptive. Expressive language is an important factor in predicting whether a child will show language disorder or not. By evaluating the naming test and the mean length of utterance (MLU) which represents expressive lexicon development and expressive grammatical development, respectively, a child’s general language development can be judged. Therefore, the purpose of this research is to ascertain whether naming ability develops at 6-month age increments by watching the naming ability development of three- to four-year-old children where the language progress takes place most rapidly. Furthermore, since it is difficult to collect and analyze data for MLU, this study attempts to predict MLU by naming ability and chronological age. The results obtained from this study could be useful as a reference in evaluating the naming development of children. Furthermore, the results may be significant for the diagnosis and treatment of language disorder by proving information related with naming development in normal children. In this study, 56 children aged from from 36 to 59 months, residing in Seoul and Kyungki area, underwent K-BNT and their spontaneous utterances were collected to examine their expressive language development. ANOVA was used to compare the average points of naming development for each age group, and regression analysis was used to investigate he results. 1. Naming accuracy increased rapidly from 36 to 41 months. However, there was no significant difference in children from 42 to 59 months. 2. There was a high positive correlation between naming accuracy and MLU. 3. There was a high positive correlation between age and MLU. 4. The positive correlation of Nnaming accuracy and age was stronger with MLUm than with MLUw. In conclusion, it can be observed that the naming ability of children progresses rapidly until around the age of 4 slows down. Likewise, it can be seen that the naming accuracy is a better variant in predicting MLU than the age. However, combining both naming accuracy and age.
