摘要：Lexical diversity is one of the language tools used to measure varied words or vocabulary produced by learners both spoken and written. This research aims to investigate lexical diversity of children narratives produced by children orally. The research design of this research is a case study supported by quantitative data. Meanwhile, the subjects of this research are seven children around 6-9 years old. Regarding data collection, the researchers employed a narrative storytelling based on a picture drawn by the subjects. Analysing data, TTR (Type-Token -Ratio) was used to measure the lexical diversity gained from the subjects by supporting relevant theories to explain the phenomena. Based on the findings, it is has been found that (1) older children have higher lexical diversity than the younger ones, (2) younger children produced higher lexical frequency (word tokens) than the older ones, and (3) individual variations showed anomalies of the result in which older children were expected to have higher lexical frequency but the result showed the reverse English.
