Ohga(2017) examined the mechanism of the interlanguage in the process of the acquisition of collocations formed with a polysemous verb by Chinese learners of Japanese from the perspective of two processes of the interactive model, typicalizing and generalizing. This study investigated how Chinese learners of Japanese understand and use the collocations formed with those synonyms by focusing on differentiating, another process of the interactive model. The results showed that although the intermediate learners did acquire appropriate collocations of each word, the meanings of which used as synonyms were unrelated. Advanced learners acquired the collocations formed with synonyms.
