SCP 4.07 and SPSS 25.0 package programs were used in the numerical analysis of the data. Data were analyzed with Mann-Whitney U and Kruskal-Wallis tests. In line with the findings, it was concluded that the vocabulary in the oral expressions of Indonesian students who learn Turkish shows a significant difference in the number of languages they know other than Turkish and the frequency of reading newspapers.
